What is a .PF file extension?

.PF file extension is created by Smith Micro. .PF has been classified as Compressed Files.

.PF is Private File

A PF file is a password-protected file compressed and encrypted by Stuffit Deluxe, a popular file compression and expansion utility. It is similar to a .SIT file, but requires a password to decrypt and decompress. PF files are often used for archiving confidential or personal data.

You can open PF files with Stuffit Deluxe in Windows or macOS. However, the PF files will not open unless the correct password is entered. Also, it is important to extract the contents of a PF file on a safe device because the contents, which may be documents, images, videos, etc., are most likely sensitive.
