BS to CAL Conversion: FAQ

What are BS files?

The BS image format is associated with the Printfox/Pagefox software programs created for the Commodore 64 brand of computers in the 1980s. Commodore 64 was one of the first highly popular models of home computers and Printfox/Pagefox programs were used as desktop publishing applications. Some of their available features included image processing and text formatting. The BS image format is currently considered obsolete and rare, so you won't find many image viewers which can open it.

What are CAL files?
