What is an .PF file?
.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.
Windows Prefetcher File
File created by Prefetcher, a component of Windows Memory Manager that speeds up the boot process and application loading; contains a trace log of Prefetcher events; records what code and data are accessed during boot and application loading processes.
PF files are typically stored in the \Windows\Prefetch\ directory. The boot process trace file always has the name NTOSBOOT-B00DFAAD.PF.
NOTE: PF files are used by Windows XP or later.
