Plug-ins
Plug-ins for extensions you remove from a file
Here you'll find descriptions of the extensions you can remove from files when you use certain plug-ins. There are "real" file extensions, which are actually used by files to denote the file type, and "made up" extensions, which are invented by the plug-in writer to allow you to specify certain actions for files.
