Requirements

• Python 3.8+ (tested on 3.12 / 3.13)
• No third-party packages — only the standard library
• The GUI needs tkinter (bundled with Windows/macOS Python and python3-tk on Linux)
• Works on Linux, Windows 10/11 and macOS

Quick start

# from the repository
python fileforge.py --help                 # list all commands
python fileforge.py gui                    # graphical interface (8 tabs)
python fileforge.py shell                  # interactive shell
python -m fileforge ls -l .                # run as a module

# see your whole computer immediately
python fileforge.py computerui             # "This PC" window: every drive, all files
python fileforge.py computer -L 2          # the same as a text tree
python fileforge.py tree . -L 3 --du       # live directory tree, no cache
python fileforge.py drives                 # volumes + free space
python fileforge.py treemap . --top 25     # terminal disk-usage chart

Install as a pip package

The project ships as a wheel (dist/locals_filesystem-2.1.0-py3-none-any.whl, published on PyPI as locals-filesystem):

pip install locals-filesystem                              # from PyPI
pip install dist/locals_filesystem-2.1.0-py3-none-any.whl  # from this folder

After installation the fileforge command is available everywhere and accepts every command in this README:

fileforge --version        # 2.1.0
fileforge help             # full command list
fileforge computerui       # "This PC" window - all drives, all files
fileforge computer -L 2    # the same machine as a text tree
fileforge tree . -L 3 --du # live directory tree, no cache
fileforge shell            # interactive shell
fileforge gui              # full GUI (8 tabs)
fileforge-gui              # GUI without a console window

Aliases and typos are understood, so all of these open the same window:

fileforge computerui   fileforge pcgui   fileforge thispcui
fileforge computrui     # <- typo, auto-corrected

To publish a new version:

python -m build            # rebuild dist/
twine upload dist/*

To build from source: pip install build && python -m build.

Every entry point understands every command

fileforge.dispatch is the single registry that knows all 57 commands (classic CLI + live tree + This PC). It is wired into all entry points, so they behave identically:

Entry point	Routes through
fileforge <cmd> (console script)	fileforge.dispatch:main
python -m fileforge <cmd>	fileforge/__main__.py → dispatch
python fileforge.py <cmd>	the launcher's own copy of the registry
fileforge.cli:main (old entry point)	re-exported to dispatch

Rebuild the wheel whenever you want the installed command to pick up the newest modules (treeview, treeui, treemap, computer, computerview, dispatch) — the dist/ artifacts are a snapshot, not a live copy.

If pip install fails while replacing Scripts\fileforge.exe (some sandboxes intercept pip's rename-to-.deleteme write), regenerate the launcher with the bundled helper instead:

python make_launchers.py                      # current environment
python make_launchers.py <path-to-Scripts>    # another environment

Live file tree & "This PC"

Everything in this section is read straight from the disk on every run. There is no cache, no index file, no background crawler: what you see is the volume as it is right now.

tree — one directory, streamed

python fileforge.py tree                    # current directory, 3 levels
python fileforge.py tree C:\ -L 2           # drive structure
python fileforge.py tree . --du --stats     # aggregated folder sizes + totals
python fileforge.py tree ~/src --ext .py --sort size --stats
python fileforge.py tree . -L 4 --json tree.json
python fileforge.py tree C:\ -L 2 --ascii --out C:\Temp\ctree.txt
python fileforge.py tree . -L 3 --top-dirs 10

iter_tree() is a generator: it emits each line the moment it is read, so memory stays proportional to the tree depth, not its size. Only --du, --json and treemap materialise the subtree (aggregation needs it).

treemap — disk usage in the terminal

python fileforge.py treemap . -L 3 --top 15 --mode both

Renders a proportional block map of the top level plus a ranked bar chart of the largest directories.

computerui — the whole machine, visible at once

python fileforge.py computerui          # opens on every drive
python fileforge.py computerui -L 3

Tab	What it shows
This PC (tree)	Root is the computer itself; every volume is a child and is expanded automatically in a background thread, rows appearing as they are read
All files	Flat table of every file on every volume — full path, size, type, modified — streamed live, cancellable with Stop

Toolbar: Depth (auto-expand levels), Max/folder, Hidden, Dirs only, Filter, Expand tree, Scan files, Stop, Export. Right-click on either tab: open, reveal in file manager, terminal here, copy path/name, properties, SHA-256. F5 refreshes, Ctrl+Q quits.

Why Max/folder matters

A single folder can hold hundreds of thousands of entries. On the machine this was developed on, D:\documents contains 303,676 entries and needs 185 s merely to enumerate — one folder would stall the entire view. Max/folder (default 500 in the window) reads only the first N entries of each folder and shows a + N more entries (not listed) marker. Set it to 0 for unlimited, or raise it when you really need everything.

With the cap in place a whole-machine depth-2 scan finishes in 3 seconds:

WHOLE MACHINE depth=2: 8258 entries, 2674 dirs, 5585 files  3.0s

Symlinks, junctions and safety

Symlinks, junctions and Windows reparse points are skipped by default — os.scandir resolves their target, and if that target is an offline network share the call blocks for minutes. The check is done before the directory is opened. Use --follow-links (or the option flag) only when you know the tree. Unreadable folders are reported inline instead of aborting the scan.

Library use

from fileforge.treeview import Options, iter_tree, build_tree, dir_sizes, to_json

for prefix, node, stats in iter_tree("D:/", Options(max_depth=2)):
    print(prefix + node.name)
print(stats.as_dict())

tree = build_tree("D:/Projects", Options(max_depth=4))
print(tree.node.agg_size, tree.node.n_files)

from fileforge.computer import iter_computer_tree, iter_all_files, volumes
for prefix, node, stats in iter_computer_tree(Options(max_depth=2, max_children=500)):
    print(prefix + node.name)
for node in iter_all_files(Options(max_depth=3), max_items=1000):
    print(node.path)

Graphical interface

python fileforge.py gui      # or: fileforge-gui after pip install

A single window with a directory tree on the left and eight tool tabs:

Tab	What you can do
Browser	Navigate, sort, copy/move/rename/delete/shred, properties, hash, archive, encrypt, open terminal or file manager, context menu
Search	All find criteria (glob, regex, ext, size, age, content, empty, depth) with a results table and right-click actions
Grep	Recursive text search with include/exclude filters; double-click jumps to the line in the built-in viewer
Integrity	Hash any file, compare two files, create/verify manifests, find duplicates and delete the extra copies
Archive	Create/extract/inspect zip & tar archives, gzip, split files into parts, merge parts back, incremental folder sync
Analytics	Summary report, extension breakdown with a bar chart, largest/newest/oldest files, empty items, broken links
Security	Encrypt/decrypt with password, shred, chmod (octal + symbolic), permission listing, world-writable audit
Text Tools	View and edit files, save, word count, regex replace with dry-run, encoding conversion

Extras: light/dark minimal theme toggle, hidden-files toggle, F5 refresh, status bar with live free space, all long jobs run on background threads.

The two tree windows

Besides the 8-tab interface above there are two dedicated viewers:

python fileforge.py treeui D:\ -L 4   # single-directory live tree
python fileforge.py computerui        # the whole computer ("This PC")
python fileforge.py treeui            # no path -> opens "This PC"

Both expand lazily (only the branch you open is ever read), offer sortable columns, a live filter, an export to .txt/.json, a light/dark theme and the same right-click actions as the main interface. computerui adds the whole-machine auto-expansion and the streaming "All files" table described above.

Interactive shell

python fileforge.py shell

ff:D:\projects> ls
ff:D:\projects> cd src
ff:D:\projects\src> find . --ext .py -l
ff:D:\projects\src> summary .
ff:D:\projects\src> !dir                 # run any native shell command
ff:D:\projects\src> exit

Builtins: cd, pwd, help, history, clear, exit / quit, and !<command> to pass through to the system shell. Every CLI command is available inside the shell with identical options.

Design notes

• Pure stdlib — no pip install required; copies of this folder run anywhere.
• Safety first — extraction guards against path traversal; --dry-run is available for rename, replace and sync.
• Structured core — src/fileforge/*.py modules (core, search, hashutil, archive, analytics, security, utils, treeview, treeui, treemap, computer, computerview) can be imported and reused as a library:

from fileforge import core, search, hashutil

core.write_text("notes.txt", "hello\n")
print(hashutil.hash_file("notes.txt", "sha256"))
for e in search.find(search.FindCriteria(root=".", extensions=[".py"])):
    print(e.rel, e.size)

• Never hangs on a bad link — the tree scanners detect symlinks, junctions and Windows reparse points before opening a directory, because os.scandir resolves their target and an offline network share would block for minutes. Huge folders are bounded by max_children (500 per folder in the GUI), and unreadable folders are reported inline instead of aborting the scan.
• Custom encryption caveat — encrypt / decrypt use a self-contained PBKDF2 + SHA-256 stream cipher with an HMAC tag. It is dependency-free and fine for personal obfuscation, but it is not audited cryptography. For sensitive data prefer age, gpg or openssl.

Testing

python tree_smoke.py        # live tree:    TOTAL 54 passed, 0 failed
python computer_smoke.py    # This PC:      TOTAL 33 passed, 0 failed
python dispatch_smoke.py    # dispatcher:   TOTAL 25 passed, 0 failed

dispatch_smoke.py checks that every catalogue entry is reachable, that all aliases resolve, that computrui auto-corrects to computerui, that an unknown command exits with code 2, and that the launcher's registry and the package's registry are identical.

Both suites drive the real CLI as a subprocess, call the library API directly and construct the Tkinter windows for real (without a blocking main loop). They need tkinter for the GUI section, which is skipped automatically when it is missing:

# Linux
sudo apt install python3-tk

The original CLI/GUI suites (smoke_test.py, gui_smoke.py) were written against the pre-src layout and are no longer part of the tree; the CLI and GUI themselves are covered by the two suites above plus python fileforge.py --help.
