What is a PET file?
Application package created for PuppyLinux; typically used for installing software programs; saved in a stored in a "tarball" compressed archive format (.TGZ files) with an md5sum checksum appended to the end.
PET stands for "Puppy's Extra Treats" and is a unified package system used by Puppy Linux 2.14 and later. PET files can be opened by the included PETget utility, or with any TGZ file extractor. When extracted, the package's directory structure is projected onto the root level of the Linux file system.
PET packages are commonly referred to as "pets." They replace .PUP files used by earlier versions of Puppy Linux.
