Troubleshoot PNM Files


Typical PNM Opening Challenges

GIMP Not Present

When you double-click your PNM file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Generally, this is experienced in %%os%% because GIMP isn't installed on your PC. The typical path of opening your PNM with a double-click won't work because %%os%% cannot make the program connection.


Tip: If you have another software that you know opens PNM files, you can select it by hitting the "Show Apps" button.


Outdated GIMP

It is possible that your version of GIMP isn't able to open your Portable Any Map Image file due to incompatibility. Visit the The GIMP Development Team website to download (or purchase) the latest version of GIMP. This issue mainly occurs when your Portable Any Map Image file was created by a newer version of GIMP than you have on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the PNM file, selecting "Properties", and looking at the version information.


Conclusion: The majority of PNM file opening issues are due to not having the correct GIMP version installed.


Other Causes of PNM File Opening Problems

Even with the correct version of GIMP installed, you can still experience difficulties opening PNMs. If you are still having problems opening PNM files, there may be other issues that are preventing you from opening these files. Additional factors include:

  • Invalid PNM file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • The PNM file description within the Windows Registry was removed
  • Incomplete or bad installation of a software application associated with the PNM format
  • File corruption affecting your PNM file
  • Past or present virus infection has affected your PNM
  • Device drivers for PNM-related hardware are out-of-date
  • Your computer does not have the adequate system resources to open the Portable Any Map Image format
