FAQ - What are pack files and how do I 'open' them?

Serif Software > CraftArtist
Applies to: CraftArtist 1 and above.

A pack file is a CraftArtist Digikit. You cannot open a pack file by double-clicking it. You can save your pack files in any location and CraftArtist will open them, providing you tell the software where you have saved them.
