Virus Database: This is the primary use. The file contains compiled virus definitions and is not meant to be opened manually.

Canvas Drawing File: In some cases, the same extension is used to hold canvas drawing information for programs like Canvas Draw (Canvas X). For these, you need the specialized drawing software. More details can be found at ACDSee.
