What is a PFILE file?
A PFILE file is a file protected with Microsoft Rights Management (RMS), an application used to protect a user's digital information. It contains a file, such as a .VSDX or .DOC file, that has been encrypted with RMS. PFILE files are generically protected whereas .PPDF, PTXT, and PJPG files are protected as read-only.
If you find a PFILE file on your computer or you receive a PFILE file as an email attachment you must install RMS to open the file. When RMS is installed you can simply double-click the file to open it. You will be prompted to confirm that you are authorized to view the file with a username and password.
NOTE: Microsoft Rights Management is also known as Azure Information Protection.
