Some file types that are read by this software include Text, Data, Audio, Video, 3D Image, Raster Image, Vector Image, Page Layout, Spreadsheet, Database, Executable, Game, CAD, GIS, Web, Plugin, Font, System, Settings, Encoded, Compressed, Disk Image, Developer, Backup and Misc among others. These have different file extensions, and this eventually resulted to a lot of users opening files that are not what they want. This version of DivX Descriptor 2 brings a much more flexible, new file format and ending the limitation of 500 characters in the name of the files.

a word of warning

Be careful not to rename the extension on .key files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .key. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
