BACKPACK file extension - Mammoet Software file
What is backpack file? How to open backpack files?
File type specification:
The BACKPACK file extension was reported to us for being used in one of the programs from Mammoet Software, such as DrawIt Lite or myCard. Seems like the developer is no longer is business and the origin and the purpose of this file type could not be verified, so it is likely obsolete.
