PSB Troubleshooting


Common PSB Opening Problems

Adobe Photoshop Not Present

When you double-click your PSB file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have Adobe Photoshop for %%os%% installed. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: When another PSB application is installed, you can choose to open it by selecting "Show Apps" and using that program.


Obsolete Version of Adobe Photoshop

Your Adobe PhotoShop Big File file is incompatible with Adobe Photoshop because you might have the wrong version installed. Installing the latest version of Adobe Photoshop from Adobe Systems Incorporated is recommended. This problem is predominately due to having a Adobe PhotoShop Big File file version that was created by a newer version of Adobe Photoshop than what you have installed on your PC.


Tip: If you right-click on your PSB file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Ultimately, most of the difficulties opening PSB files are due to having the wrong version of Adobe Photoshop installed.


Other Causes of PSB File Opening Problems

Even with the correct version of Adobe Photoshop installed, you can still experience difficulties opening PSBs. If you are still having problems opening PSB files, there may be other issues that are preventing you from opening these files. Other contributing causes:

  • PSB file type Registry entries are wrong
  • Deletion of the PSB file description from the Registry by mistake
  • Corrupt install of Adobe Photoshop or other PSB-related program
  • PSB file corruption
  • The PSB is infected with a virus
  • Device drivers of the hardware associated with your PSB file are corrupt or out-of-date
  • Your computer does not have the adequate system resources to open the Adobe PhotoShop Big File format
