What is a PDI file?
A .PDI file is a multi-use file extension. The most common use is a process display file created by OSIsoft PI ProcessBook or a Plant Display Interface used by iFIX SCADA. These files store graphical representations of industrial plant systems and live data.
Other software programs also use the .PDI extension. It can be a machine diagnostics data archive from Schneider Electric ELAU, which is typically stored as a compressed ZIP file. It might also be a construction takeoff estimate file used by PlanSwift.
In the media and gaming sectors, a .PDI file can be a DiscJuggler disc image by Padus, a Portable Document Image in CyberLink PhotoDirector, a Playdate Image by Panic, or an InstantCopy Disc Image by Pinnacle Systems.
How to open PDI files?
Because .PDI files have many different formats, you must know which software created your specific file. You can open industrial display files with PI ProcessBook or iFIX SCADA. You can mount an InstantCopy Disc Image using virtual drive software. You can extract diagnostic archives with standard compression utilities like 7-Zip.
viewer.online/pdi analyzes .PDI files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because the primary .PDI files use the known DOC format and others use the ZIP format, viewer.online/pdi can safely open and display them online, eliminating compatibility problems. If your .PDI file has multiple possible meanings, we recommend using viewer.online/pdi to identify the actual format of your file.
