Question or Symptom
When I set up a file type mapping to the extension .zip, I specified PkZip instead of PkUnZip. How can I fix this?
Resolution
In Windows Explorer select Folder Options. Then select the File Types tab. Select the extension you're set up incorrectly and press the Edit button.
From this screen select Edit again and you'll see a text widget named "Application used to perform action". You can type in the full path to the appropriate program, or just use the Browse button to find the appropriate program.
