13 File Extension

Have a problem opening a .13 file? We collect information about file formats and can explain what 13 files are. Additionally we recommend software suitable for opening or converting such files.

What is the .13 file type?

Along with other numerical extensions, the .13 extension has its primary association with the Pro/Engineer Versioned Project file type. Pro/Engineer is the PTC's flagship CAD (Computer-Aided Design) software system, highly complex and exceedingly powerful. Pro/Engineer finds its use in a range of technology-intensive areas, incl. shipbuilding, automotive, medical, space and many other industries.

Every time any current project worked upon in the Pro/Engineer environment is saved, a different file is created—a versioned project. Such a versioned project file would have a numerical extension appended to its original extension (e.g., ".1" for the first version, etc.). Thus, the .13 extension would denote the thirteenth version of a Pro/Engineer project file.

Alternatively, the .13 extension is used to identify game music files that belong to the Salt Lake Winter Olympics 2002 computer game (PC/PlayStation/GBA) by Eidos Interactive/Ubisoft. The game uses such binary .13 files to store compressed in-game music tracks. Such .13 files are not intended to and cannot be opened directly for playback.

Also, the ".13" string can sometimes look like a filename extension on MS Windows machines with the "Hide extensions..." option turned on (default). In fact, in most cases it is just a dotted part of the filename, e.g. to indicate the file's current version like in "[filename].13[.hidden_extension]". To avoid confusion, the "Hide extensions..." option should be always turned off, so that the actual extension and file type can be seen.
