0. Import the FileManager class.

   from pyfilemanager import FileManager
   

1. Initialize the file manager.

   fm = FileManager(r'C:\videos', exclude_hidden=True)
   

2. Add files based on different inclusion and exclusion criteria. Use the include parameter to keep file paths that contain all of the supplied strings anywhere in the file path. Use the exclude parameter to disregard file paths that contain any of the supplied string anywhere in the file path.

    fm.add('canon', '*Camera.avi', include='canon')
    # file path must contain canon
   
    fm.add('sony42', '*Camera.avi', include=['sony', '42'])
    # file path must contain sony AND 42
    # grabs one file - sony\142Camera.avi
    
    fm.add('videos', ['*.avi', '*.mp4'])
    # add multiple conditions by supplying them as a list or tuple
    
    fm.add('panasonic', '*.avi', include='panasonic', exclude='panasonic2')
    # grab videos in the panasonic folder
    
    fm.add('notes', 'notes*.txt')
    # grab all notes
   
    fm.add('notes', 'notes*.txt', include='notes\\notes')
    # grab notes from the notes folder
    # this will overwrite the previous notes entry
   
    fm.add('notes', 'notes*.txt', exclude=['sony', 'panasonic', 'panasonic2', 'canon'])
    # achieves the same result as the previous line
   

3. Retrieve file paths using a dict-like convention.

    fm['canon']
    # Retrieve by the tag 'canon'
    # Returns canon/40Camera.avi and canon/51Camera.avi
   
    fm['143Camera']
    # When a tag is not found, retrieve file paths by an exact match to the file stem.
    # Returns panasonic/143Camera.avi and sony/143Camera.avi
   
    fm['20']
    # If the key doesn't match a tag or a stem of a filename, do a loose-search to retrieve all entries where the tag is anywhere in the full path.
    # Returns panasonic2/201Camera.avi and panasonic2/202.mp4
   
    fm['notes?.txt']
    # Search for files using special chracters *, ?, !, [] specified in fnmatch
    # Returns notes/notes1.txt and notes/notes2.txt
   

4. Add and retrieve in one line of code.

   fm.add('canon', '*Camera.avi', include='canon')['canon']
   # Note that the method returns the instance of the FileManager object. 
   

5. Retrieve all the added keys using fm.get_tags()

   fm.get_tags()
   # returns a list ['canon', 'sony42', 'videos', 'panasonic', 'notes']
   

6. Retrieve paths of all the added files.

   fm.all_files
   

7. Get a report of the number of files, and the occupied space.

    fm.report()
   

   2 canon files taking up 0.000 MB
   1 sony42 files taking up 0.000 MB
   8 videos files taking up 0.000 MB
   2 panasonic files taking up 0.000 MB
   5 txt files taking up 0.000 MB
