What is a PQI file

PQI files mostly belong to PQI Image.

The PQI file can serve different functions depending on its source. In most cases, it is used as a disk image backup file. This means that the file stores a complete copy of a drive, which can be used for system recovery or restoration.
Other uses include:

  • Disk Image Backup: some of these files are created by products like PQI Image, and they are known as drive image backup files. They capture the contents of a drive exactly.
  • Siemens PLC Backup: some are used as backups for Siemens PLC systems. These are also described as PowerQuest Partition Image backups and are associated with ProTool.
  • Phreeqc Interactive Input: some serve as input files for the Phreeqc geochemical software. For more details, you may visit the USGS Phreeqc webpage. This version is used to run chemical simulations.

FilExt.com tip: To open or view a PQI file, it is important to use the original software provided by the related company, as they usually incorporate the necessary decoding for the backup or image data. Opening these files in a standard text editor will not display the intended information.

How to open PQI files

You need a suitable software like PQI Image to open a PQI file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PQI file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PQI file directly in the browser:. Just drag the file onto this browser window and drop it.
