Ever find a file online with a file extension you aren’t familiar with? Whenever I find myself in this boat, I find FILExt is an invaluable resource.

FILExt has thousands of file extensions in its database. A file extension, if you don’t know, specifies which type of file a file is by add an extension like .doc to the file name. Many operating systems now hide these by default but can easily be made visible.

I’ve never found an extension FILExt doesn’t have. Users contribute file extensions to the site in order to keep it up to date and full.

Often, but not all that often, FILExt doesn’t provide much information on a certain format however it will generally provide information on which company makes the software which produces that format providing a good starting point to opening an alien file format!

Heck! It has 3 possibilities for what a .bob file could be!
