Change the File Extension

If you accidentally save a different file type with a .PSD extension, Photoshop will quickly detect the respective file is not really a Photoshop document. As a result, it won’t open it. Make sure the extension matches the actual file type.

Check File Extension Type on Windows

  1. Right-click on the problematic file and select Properties.
  2. Check the type of file.
  3. Then right-click on the file again, and select Rename.
  4. Delete the false PSD extension. Change the file extension to the correct extension.
  5. Check if Photoshop can now open the file.

Check File Extension Type on Mac

Select your file, and click on the File menu. Then click on Get Info. Locate the Name & Extension section, and click on the arrow to expand the section.

If you want to show the extensions for all of your files, launch Finder, and click on Preferences. Then go to the Advanced tab and tick the “Show all filename extensions” checkbox.

Then change the extension to the right extension type. By the way, many macOS users confirmed that changing the extension to .tiff allowed them to open their files with all the layers intact.

Check for Updates

Update Photoshop and your OS to the latest version. Click on the Help menu and select Updates. The Adobe Creative Cloud App will launch. Simply hit the Update button to install the latest updates.

Then check for OS updates.

  • On Windows, go to Settings and click Updates and Security. Go to Windows Update, and hit the Check for updates button.
  • On macOS, go to System Preferences, and select Software Update.

Other Solution

Rename the file so that the file name extension matches the correct file type. (mydocument.jpg)
