Opening PUP files

Did your computer fail to open a PUP file? We explain what PUP files are and recommend software that we know can open or convert your PUP files.

What is a PUP file?

Files that contain the .pup file extension are most commonly associated with the Puppy Linux operating system. Puppy Linux was created to be a user-friendly version of the free Linux operating system.

A PUP file is run when an installer program is opened on the user's computer when that computer is running on Puppy Linux. These files are similar to the installer.exe files that are used with the applications that are run on Windows, but the PUP are used for applications that run on the Puppy Linux OS instead.

PUP files are commonly referred to as "Dot Pup" files.

The PlayStation 3 gaming device also uses the .pup file suffix. These PUP files contain update files for the PlayStation 3 hardware.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
