Discord as a filesystem. Version 1.3.1.

This is a program/bot allowing you to use Discord as your free, unlimited cloud-storage. You assign a channel, mount the filesystem and let the bot do the rest.

Note that this is mainly an experimental program and not something made, or at least intended, to be used seriously.

First off, you'll need Linux to run this (with FUSE and a modern version of Python installed, should already be installed by default on most distros). All testing and official support is for Ubuntu 23.10 with Python 3.11 and the preinstalled libraries. If you have issues with another (Linux) system I will of course try and look into it anyways!

Before using the program, you will need to do some setup. I will assume you are techy enough to do this yourself, so this will be in broad terms what to do.

• Import libraries in requirements.txt
• Create (or use) a discord bot for the FS
• Fill in data in file fat.json (see below)

After this is done you should be good to go. The program is started by executing dc-fs.py with a modern Python version, and closing it should be done by unmounting the filesystem. You can optionally specify another mountpoint as a command-line argument, otherwise the default mountpoint in fat.json will be used.

The File Allocation Table, or FAT for short, along with the configuration data is stored in the file fat.json. Replacing it will essentially replace the entire filesystem, corrupting or losing it will be irrecoverable in most cases. If the file is not present it will be created at runtime and you will be prompted to fill in some data.

The data (in default order) which you need to fill in is the following:

• token - Bot token (string): The Discord bot token
• mount - Mountpoint (string/path): Absolute or relative path to the filesystem mountpoint, ./mnt/ by default
• channel - Filesystem channel (integer): The ID of the channel the filesystem operates in

If you have upgraded from an older version of the program it might be a good idea to run convert.py. This will make sure the FAT is up-to-date and compatible with the newest program version, so you don't experience data loss.

I plan to fix many of these limitations in later versions of the program, but until then it is good if you know about them.

• The filesystem is, of course, quite slow (especially for large files)
• 175MiB max file size (7x Discord limit, max total size for a single message)
• No support for directories
• Files are fully accessible by anyone with access to the filesystem channel
• Multiple clients cannot operate on the same filesystem
• No file permissions checks supported, that is considered out of scope

Here is a list of all currently known bugs, prioritized by functionality impact.

These bugs will be fixed in the next patch release.

These bugs will either be fixed in the next patch release or minor release.

These bugs will be fixed whenever there is time, but most likely in a future minor release.

• Copies of files in the FS channel that is unknown to the program may occur under very special conditions

Updated versions of this program will be released continuously (whenever I decide to work on it).

Although I try not to, there is no guarantee that new versions won't break data stored in older versions. However, if something breaks (and I'm aware) it will be noted in the release notes. The convert.py script should also be used after upgrading (especially if noted in release notes).

Below is how I currently plan on going forward with the project.

• Fix bugs or minor issues as they appear

• Unlimited file size by splitting into multiple messages

• Implement directories
• Encryption of files (and obfuscation of filenames)
• File integrity verification
• Cache files for a short while after closing them to save time on up- and downloads

• Asynchronized filesystem operations
• Generalizing the concept for more hosts or access methods
• Multiple clients connected to the same filesystem
