Use templates to automatically move files into directories

autofile

Command line app (written in python) to automatically move or copy files based on metadata associated with the files. For example, file your photos based on EXIF metadata or use MP3 tags to file your music files.

autofile uses a template system to specify the target directory and/or filename based on the file's metadata. For example:

autofile *.mp3 --target ~/Music --directory "{audio:artist}/{audio:album}"

Will move all mp3 files to new folders with Artist/Album naming scheme.

The template system is very flexible and powerful allowing you to perform transforms on the metadata fields and use conditional logic.

autofile understands metadata about audio files (MP3, OGG, etc), photo & video files, macOS specific metadata such as Finder tags as well as various filesystem related metadata.

Photo and video metadata (EXIF, IPTC, XMP, etc.) requires that the third-party exiftool command line utility be installed. All other metadata works with no additional dependencies.

Examples

File image files into directory structure with format "Camera Make/Year/Month/file.jpg":

$ ls -l ~/Pictures/NewPhotos
total 12160
-rw-r--r--@ 1 user  staff  3449684 Oct 24 07:10 IMG_1234.jpeg
-rw-r--r--@ 1 user  staff  2771656 Oct 23 12:53 IMG_1235.jpg

$ autofile --target ~/Pictures/FiledPhotos \
--directory "{exiftool:Make}/{exiftool:created.year}/{exiftool:created.month}" \
~/Pictures/NewPhotos/*

Supported Platforms

Currently tested on macOS and Ubuntu Linux. Tested on macOS 10.15.7 (Catalina) but should work fine on newer versions. Some of the features such as Finder tags are macOS specific and will not be available on other platforms.

On macOS, copy and move use native macOS API calls to take advantage of advanced features such as copy-on-write that are not available with the standard python system calls.

Cautions and Warnings

This software is feature complete but not yet fully tested. No warranty of any kind is implied or provided. Please ensure you have a backup before using this software as it can rename and move your files with no undo feature. I recommend you always run autofile with the --dry-run flag first to ensure you understand exactly what it will do.

Contributions

Contributions of all kinds are welcome! If you find a bug or have an idea to improve autofile, please open an issue!

Template System

autofile contains a rich templating system which allows fine-grained control   
over the output format of metadata. The templating system converts one or      
template statements, written in metadata templating language (MTL), to one or  
more rendered values using metadata information from the file being processed. 

In its simplest form, a template statement has the form: "{template_field}",   
for example "{size}" which resolves to the size of the file. Template fields   
may also have subfields delineated by a : as in "{audio:artist}" which resolves
to the artist name for an audio file (e.g. mp3).  In this example, the field is
audio and the subfield is artist.  Template fields may also have attributes    
delineated by a . as in "{created.year}" which resolves to the 4-digit year of 
the file creation date. In this example, the field is created and the attribute
is year.                                                                       

Template statements may contain one or more modifiers.  The full syntax is:    

"pretext{delim+template_field:subfield|filter[find,replace]                    
conditional?bool_value,default}posttext"                                       

Template statements are white-space sensitive meaning that white space (spaces,
tabs) changes the meaning of the template statement.                           

pretext and posttext are free form text.  For example, if an image file has    
Title (e.g. XMP:Title) "My file Title". the template statement "The title of   
the file is {exiftool:Title}", resolves to "The title of the file is My file   
Title".  The pretext in this example is "The title if the file is " and the    
template_field is {Title}.  Note: some punctuation such as commas cannot be    
used in the pretext or posttext.  For this reason, the template system provides
special punctuation templates like {comma} to insert punctuation where needed. 
For example: {exiftool:Make}{comma}{exiftool:Model} could resolve to           
Apple,iPhone SE.                                                               

Delimiter                                                                      

delim: optional delimiter string to use when expanding multi-valued template   
values in-place                                                                

+: If present before template name, expands the template in place.  If delim   
not provided, values are joined with no delimiter.                             

e.g. if image file keywords are ["foo","bar"]:                                 

 • "{exiftool:Keywords}" renders to "foo", "bar"                               
 • "{,+exiftool:Keywords}" renders to: "foo,bar"                               
 • "{; +exiftool:Keywords}" renders to: "foo; bar"                             
 • "{+exiftool:Keywords}" renders to "foobar"                                  

template_field: The template field to resolve.                                 

:subfield: Templates may have sub-fields; reserved for future use.             

Filters                                                                        

|filter: You may optionally append one or more filter commands to the end of   
the template field using the vertical pipe ('|') symbol.  Filters may be       
combined, separated by '|' as in: {user|capitalize|parens}.                    

Valid filters are:                                                             

 • lower: Convert value to lower case, e.g. 'Value' => 'value'.                
 • upper: Convert value to upper case, e.g. 'Value' => 'VALUE'.                
 • strip: Strip whitespace from beginning/end of value, e.g. ' Value ' =>      
   'Value'.                                                                    
 • titlecase: Convert value to title case, e.g. 'my value' => 'My Value'.      
 • capitalize: Capitalize first word of value and convert other words to lower 
   case, e.g. 'MY VALUE' => 'My value'.                                        
 • braces: Enclose value in curly braces, e.g. 'value => '{value}'.            
 • parens: Enclose value in parentheses, e.g. 'value' => '(value').            
 • brackets: Enclose value in brackets, e.g. 'value' => '[value]'.             
 • split(x): Split value into a list of values using x as delimiter, e.g.      
   'value1;value2' => ['value1', 'value2'] if used with split(;).              
 • autosplit: Automatically split delimited string into separate values (for   
   example, keyword string in docx files); will split strings delimited by     
   comma, semicolon, or space, e.g. 'value1,value2' => ['value1', 'value2'].   
 • chop(x): Remove x characters off the end of value, e.g. chop(1): 'Value' => 
   'Valu'; when applied to a list, chops characters from each list value, e.g. 
   chop(1): ["travel", "beach"]=> ["trave", "beac"].                           
 • chomp(x): Remove x characters from the beginning of value, e.g. chomp(1):   
   ['Value'] => ['alue']; when applied to a list, removes characters from each 
   list value, e.g. chomp(1): ["travel", "beach"]=> ["ravel", "each"].         
 • sort: Sort list of values, e.g. ['c', 'b', 'a'] => ['a', 'b', 'c'].         
 • rsort: Sort list of values in reverse order, e.g. ['a', 'b', 'c'] => ['c',  
   'b', 'a'].

 • uniq: Remove duplicate values, e.g. ['a', 'b', 'c', 'b', 'a'] => ['a', 'b', 
   'c'].                                                                       
 • join(x): Join list of values with delimiter x, e.g. join(:): ['a', 'b', 'c']
   => 'a:b:c'; the DELIM option functions similar to join(x) but with DELIM,   
   the join happens before being passed to any filters.                        
 • append(x): Append x to list of values, e.g. append(d): ['a', 'b', 'c'] =>   
   ['a', 'b', 'c', 'd'].                                                       
 • prepend(x): Prepend x to list of values, e.g. prepend(d): ['a', 'b', 'c'] =>

 • appends(x): [append s(tring)] Append x to each value of list of values, e.g.
   appends(d): ['a', 'b', 'c'] => ['ad', 'bd', 'cd'].                          
 • prepends(x): [prepend s(tring)] Prepend x to each value of list of values,  
   e.g. prepends(d): ['a', 'b', 'c'] => ['da', 'db', 'dc'].                    
 • remove(x): Remove x from list of values, e.g. remove(b): ['a', 'b', 'c'] => 
   ['a', 'c'].                                                                 
 • slice(start:stop:step): Slice list using same semantics as Python's list    
   slicing, e.g. slice(1:3): ['a', 'b', 'c', 'd'] => ['b', 'c']; slice(1:4:2): 
   ['a', 'b', 'c', 'd'] => ['b', 'd']; slice(1:): ['a', 'b', 'c', 'd'] => ['b',
   'c', 'd']; slice(:-1): ['a', 'b', 'c', 'd'] => ['a', 'b', 'c']; slice(::-1):
   ['a', 'b', 'c', 'd'] => ['d', 'c', 'b', 'a']. See also sslice().            
 • sslice(start:stop:step): [s(tring) slice] Slice values in a list using same 
   semantics as Python's string slicing, e.g. sslice(1:3):'abcd => 'bc';       
   sslice(1:4:2): 'abcd' => 'bd', etc. See also slice().                       

e.g. if file keywords are ["FOO","bar"]:                                       

 • "{exiftool:Keywords|lower}" renders to "foo", "bar"                         
 • "{exiftool:Keywords|upper}" renders to: "FOO", "BAR"                        
 • "{exiftool:Keywords|capitalize}" renders to: "Foo", "Bar"                   
 • "{exiftool:Keywords|lower|parens}" renders to: "(foo)", "(bar)"             

e.g. if an image file description is "my description":                         

 • "{exiftool:Description|titlecase}" renders to: "My Description"             

Find/Replace                                                                   

[find,replace]: optional text replacement to perform on rendered template      
value.  For example, to replace "/" in a a keyword, you could use the template 
"{exiftool:Keywords[/,-]}".  Multiple replacements can be made by appending "|"
and adding another find|replace pair.  e.g. to replace both "/" and ":" in     
keywords: "{exiftool:Keywords[/,-|:,-]}".  find/replace pairs are not limited  
to single characters.  The "|" character cannot be used in a find/replace pair.

Conditional Operators                                                          

conditional: optional conditional expression that is evaluated as boolean      
(True/False) for use with the ?bool_value modifier.  Conditional expressions   
take the form 'not operator value' where not is an optional modifier that      
negates the operator.  Note: the space before the conditional expression is    
required if you use a conditional expression.  Valid comparison operators are: 

 • contains: template field contains value, similar to python's in             
 • matches: template field contains exactly value, unlike contains: does not   
   match partial matches                                                       
 • startswith: template field starts with value                                
 • endswith: template field ends with value                                    
 • <=: template field is less than or equal to value                           
 • >=: template field is greater than or equal to value                        
 • <: template field is less than value                                        
 • >: template field is greater than value                                     
 • ==: template field equals value                                             
 • !=: template field does not equal value                                     

Multiple values may be separated by '|' (the pipe symbol) when used with       
contains, matches, startswith, and endswith.  value is itself a template       
statement so you can use one or more template fields in value which will be    
resolved before the comparison occurs. When applied to multi-valued fields (ie.
lists), the comparison is applied to each value in the list and evaluates to   
True if any of the values match.                                               

For example:                                                                   

 • {exiftool:Keywords matches Beach} resolves to True if 'Beach' is a keyword. 
   It would not match keyword 'BeachDay'.                                      
 • {exiftool:Keywords contains Beach} resolves to True if any keyword contains 
   the word 'Beach' so it would match both 'Beach' and 'BeachDay'.             
 • {ISO < 100} resolves to True if the file's ISO is < 100.                    
 • {exiftool:Keywords|lower contains beach} uses the lower case filter to do   
   case-insensitive matching to match any keyword that contains the word       
   'beach'.                                                                    
 • {exiftool:Keywords|lower not contains beach} uses the not modifier to negate
   the comparison so this resolves to True if there is no keyword that matches 
   'beach'.                                                                    
 • {docx:author startswith John} resolves to True if the author of a docx file 
   starts with 'John'.                                                         
 • {audio:bitrate == 320} resolves to True if the audio file's bitrate is 320  
   kbps.                                                                       

Boolean Values                                                                 

?bool_value: Template fields may be evaluated as boolean (True/False) by       
appending "?" after the field name or "[find/replace]".  If a field is True or 
has any value, the value following the "?" will be used to render the template 
instead of the actual field value.  If the template field evaluates to False or
has no value (e.g. file has no title and field is "{audio:title}") then the    
default value following a "," will be used.                                    

e.g. if file has a title                                                       

 • "{audio:title?I have a title,I do not have a title}" renders to "I have a   
   title"                                                                      

and if it does not have a title:                                               

 • "{audio:title?I have a title,I do not have a title}" renders to "I do not   
   have a title"                                                               

Default Values                                                                 

,default: optional default value to use if the template name has no value.     
This modifier is also used for the value if False for boolean-type fields (see 
above) as well as to hold a sub-template for values like {created.strftime}.   
If no default value provided and the field is null, autofile will use a default
value of '_' (underscore character).                                           

Template fields such as created.strftime use the default value to pass the     
template to use for strftime.                                                  

e.g., if file date is 4 February 2020, 19:07:38,                               

 • "{created.strftime,%Y-%m-%d-%H%M%S}" renders to "2020-02-04-190738"         

Special Characters                                                             

If you want to include "{" or "}" in the output, use "{openbrace}" or          
"{closebrace}" template substitution.                                          

e.g. "{created.year}/{openbrace}{audio.title}{closebrace}" would result in     
"2020/{file Title}".                                                           

Field Attributes                                                               

Some templates have additional modifiers that can be appended to the template  
name using dot notation to access specific attributes of the template field.   
For example, the {filepath} template returns the path of the file being        
processed and {filepath.parent} returns the parent directory.                  

Variables                                                                      

You can define variables for later use in the template string using the format 
{var:NAME,VALUE}.  Variables may then be referenced using the format %NAME. For
example: {var:foo,bar} defines the variable %foo to have value bar. This can be
useful if you want to re-use a complex template value in multiple places within
your template string or for allowing the use of characters that would otherwise
be prohibited in a template string. For example, the "pipe" (|) character is   
not allowed in a find/replace pair but you can get around this limitation like 
so: {var:pipe,{pipe}}{audio:title[-,%pipe]} which replaces the - character with
| (the value of %pipe).                                                        

Variables can also be referenced as fields in the template string, for example:
{var:year,{created.year}}{filepath.stem}-{%year}{filepath.suffix}. In some cases,
use of variables can make your template string more readable.  Variables can be
used as template fields, as values for filters, as values for conditional      
operations, or as default values.  When used as a conditional value or default 
value, variables should be treated like any other field and enclosed in braces 
as conditional and default values are evaluated as template strings. For       
example: `{var:name,John}{docx:author contains {%name}?{%name},Not-{%name}}    

If you need to use a % (percent sign character), you can escape the percent    
sign by using %%.  You can also use the {percent} template field where a       
template field is required. For example:                                       

{audio:title[:,%%]} replaces the : with % and {audio:title contains            
Foo?{audio:title}{percent},{audio:title}} adds % to the audio title if it      
contains Foo.                                                                  

Punctuation Fields                                                             

Field           Description
{comma}         A comma: ','
{semicolon}     A semicolon: ';'
{questionmark}  A question mark: '?'
{pipe}          A vertical pipe: '|'
{percent}       A percent sign: '%'
{openbrace}     An open brace: '{'
{closebrace}    A close brace: '}'
{openparens}    An open parentheses: '('
{closeparens}   A close parentheses: ')'
{openbracket}   An open bracket: '['
{closebracket}  A close bracket: ']'
{newline}       A newline: '\n'
{lf}            A line feed: '\n', alias for {newline}
{cr}            A carriage return: '\r'
{crlf}          a carriage return + line feed: '\r\n'

Within the template system, many punctuation characters have special meaning,  
e.g. {} indicates a template field and this means that some punctuation        
characters cannot be inserted into the template. Thus, if you want to insert   
punctuation into the rendered template value, you can use these punctuation    
fields to do so. For example, {openbrace}value{closebrace} will render to      
{value}.                                                                       

String Formatting Fields                                                       

Field     Description
{strip}   Use in form '{strip,TEMPLATE}'; strips whitespace from beginning and
          end of rendered TEMPLATE value(s).
{format}  Use in form, '{format:TYPE:FORMAT,TEMPLATE}'; converts TEMPLATE value
          to TYPE then formats the value using python string formatting codes
          specified by FORMAT; TYPE is one of: 'int', 'float', or 'str'.

The {strip} and {format} fields are used to format strings. {strip,TEMPLATE}   
strips whitespace from TEMPLATE. For example, {strip,{exiftool:Title}} will    
strip any excess whitespace from the title of an image file.                   

{format:TYPE:FORMAT,TEMPLATE} formats TEMPLATE using python string formatting  
codes. For example:                                                            

 • {format:int:02d,{audio:track}} will format the track number of an audio file
   to two digits with leading zeros.                                           
 • {format:str:-^30,{audio.title}} will center the title of an audio file and  
   pad it to 30 characters with '-'.                                           

TYPE must be one of 'int', 'float', or 'str'.                                  

FORMAT may be a string or an variable. A variable may be helpful when you need 
to use a character in the format string that would otherwise not be allowed.   
For example, to use a comma separator, you could do this:                      

{var:commaformat,{comma}}{format:int:%commaformat,{created.year}} which        
transforms "2021" to "2,021"                                                   

See https://docs.python.org/3.7/library/string.html#formatspec for more        
information on valid FORMAT values.                                            

File Information Fields                                                        

Field    Description
{size}   Size of file in bytes
{uid}    User identifier of the file owner
{gid}    Group identifier of the file owner
{user}   User name of the file owner
{group}  Group name of the file owner

Date/Time Fields                                                               

Field       Description
{created}   File creation date/time (MacOS only; only other platforms returns
            file inode change time)
{modified}  File modification date/time
{accessed}  File last accessed date/time
{today}     The current date/time (as of when {today} is first evaluated)
{now}       The current date/time (evaluated at the time the template is
            processed)

Date/time fields may be formatted using "dot notation" attributes which are    
appended to the field name following a . (period). For example, {created.month}
resolves to the month name of the file's creation date in the user's locale,   
e.g. December.                                                                 

The {today} and {now} fields resolve to the current date/time with one key     
distinction between them: {today} is the current date/time as of when {today}  
is first evaluated and will remain unchanged for every file processed; {now} is
the current date/time at the time each template is processed and will change   
with every file processed.                                                     

The following attributes are available:

min        2-digit minute, e.g. 15
sec        2-digit second, e.g. 30
strftime   Apply strftime template to date/time. Should be used in form
           {created.strftime,TEMPLATE} where TEMPLATE is a valid strftime
           template, e.g. {created.strftime,%Y-%U} would result in year-week
           number of year: '2020-23'. If used with no template will return null
           value. See https://strftime.org/ for help on strftime templates.

File Path Fields                                                               

Field       Description
{filepath}  The full path to the file being processed

The {filepath} fields returns the full path to the source file being processed.
Various attributes of the path can be accessed using "dot notation" (appended  
to the filepath field with a '.'). For example, {filepath.name} returns just   
the name of the file without the full path. {filepath.parent} returns the      
parent directory of the file.                                                  

Path attributes can be chained, for example {filepath.parent.name} returns just
the name of the immediate parent directory without the full directory path.    

For example, if the field {filepath} is '/Shared/files/IMG_1234.JPG':          

 • {filepath.parent} is '/Shared/files'                                        
 • {filepath.name} is 'IMG_1234.JPG'                                           
 • {filepath.stem} is 'IMG_1234'                                               
 • {filepath.suffix} is '.JPG'                                                 

The following attributes are available:                                        

Subfield  Description
name      The name of the file
stem      The name of the file without the suffix (extension)
suffix    The suffix (extension) of the file, including the leading `.`
parent    The parent directory of the file

Field   Description
{mdls}  Get metadata attributes for file as returned by mdls command; use in
        form '{mdls:ATTRIBUTE}', for example, '{mdls:kMDItemContentType}'

{mdls:ATTRIBUTE} returns the value of the metadata ATTRIBUTE as returned by the
macOS mdls command. For example, {mdls:kMDItemContentType} returns the content 
type of the file, e.g. public.python-script or public.mp3 and                  
{mdls:kMDItemKind} returns a description of file type, e.g. Python Script or

Photo and Video Files                                                          

Field       Description
{exiftool}  Format: '{exiftool:GROUP:TAGNAME}'; use exiftool
            (https://exiftool.org) to extract metadata, in form GROUP:TAGNAME
            or TAGNAME, from image. E.g. '{exiftool:Make}' to get camera make,
            or {exiftool:IPTC:Keywords} to extract keywords. See
            https://exiftool.org/TagNames/ for list of valid tag names.  Group
            name is optional (e.g. EXIF, IPTC, etc) but if specified, should be
            the same as used in `exiftool -G`, e.g. '{exiftool:EXIF:Make}'.
            exiftool must be installed in the path to use this template field
            (https://exiftool.org/).

The {exiftool} template uses the third-party exiftool app                      
(https://exiftool.org) to extract metadata from photo and video files.         

It must be used with one or more subfields which are exiftool tags, for        
example: {exiftool:EXIF:Make} for camera make, or {exiftool:IPTC:Keywords} for 
keywords. The exiftool Group name (e.g. IPTC) is optional.                     

There are two derived subfields: created and modified which represent the      
created date or the modified date, respectively. These subfields are datetime  
values and you can access the various attributes of the datetime by using an
