What is a PST file?
A .PST file is an Outlook Personal Information Store file. Microsoft uses this format for Microsoft Outlook. It stores emails, contacts, calendar events, and tasks on a local hard drive. Less commonly, a .PST file can be a CNC machine post-processor file used by CAM software like ESPRIT, Edgecam, or Mastercam.
How to open PST files?
To open a standard .PST email archive, you usually need Microsoft Outlook. You can import the file into the software to read your messages. System administrators also use command-line tools like `readpst` from the libpst library on Linux to extract data and read the structure.
