What is a .psc file?

A .psc file is a 3M Printscape (version 2). This is an archive — a container holding other files, usually compressed. Confusingly, this extension has been used by 2 different formats over the years — they're all listed below.

This extension has been used by more than one format

2 different formats have claimed .psc over the years, so two files with the same extension aren't necessarily the same kind of thing.

How to open a .psc file

  • 7-Zip (Windows) or Keka / The Unarchiver (Mac) extract most archive formats, including old ones.
  • On Linux, try `7z x`, `unar` or Ark.

The registry records this extension against 3M Printscape, PaintShop Plus Compressed Format, so software from that family is the most likely match.

How to convert a .psc file

  • Extract the contents, then re-compress as .zip if you need to share them widely.
