Let's Solve the File Format Problem!

Floppy disk or bar code, ZIP or GIF or DBF or DOC, Windows Registry or Commodore BASIC... if it holds data, it's probably documented here. See the live Twitter feed of formats being solved!

First Time Visiting This Wiki? Please read the Statement of Project to understand why this project exists. Then check out the FAQ for some frequently asked questions about the project and its goals and procedures. Finally, brush up on the guidelines for Editing.

Ready to Edit? You should be able to create a new account right away! Come on IRC (#justsolve @ EFNet) if you want to chat about stuff. Browse the File Formats list to get ideas. We've been collecting Sources to pull from. (Or be a source yourself!) Read the To Do List, or the Most Needed Articles. There's lots of Roles to play on here.

Or are you just looking for file format information? This project is still in a development phase, so it is mostly focused on editors at this point, but if you're coming here as an end-user looking for information on some files, disks, tapes, or other data you've stumbled upon, there may be information of use. You can try navigating the hierarchy of data types at File Formats (which, despite the name, includes a bunch of other things like physical media formats). Or, if you found a file and don't know what it is, but at least it's got a file extension (those letters at the end of the filename after a dot), you might try browsing the file formats by extension category. Good luck!
