What is a .PFI file?
A .PFI file primarily represents a PhotoFiltre Studio Image. These files are created by PhotoFiltre Studio, a popular image editing application. The format stores multi-layered images, allowing users to save edits, text, and adjustments without flattening the picture. However, the .PFI extension is also used for other data types. It can be an electrical drawing project file for ProfiCAD, a disk image index file for Paragon Software, a backup file format for Veritas Backup Exec, or a firmware update for PLUM ecoMAX controllers.
How to open .PFI files?
If your file is a PhotoFiltre Studio Image, you must open it with PhotoFiltre Studio. If it is an electrical drawing, you need ProfiCAD. If it is a backup index, it requires Paragon or Veritas software. Because the .PFI extension has multiple possible meanings, you might see errors if you try to open the file with the wrong program.
Software and tools
If you are not sure what program created your file, you can use viewer.online/pfi to analyze .PFI files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
Because a single extension can represent a photo, an electrical drawing, or a system backup, viewer.online/pfi is useful for identifying, inspecting, and understanding .PFI files without installing software or dealing with compatibility problems.
