Why can’t I unzip files in Vista?
In Windows XP, you can unzip files by double-clicking on it or by right-clicking on it and using the context menu. When I tried this on Vista, the menu was not visible? Did Microsoft remove that feature?
Apparently, I installed ZipGenuis 6 recently but uninstalled it quickly after it had difficulty with some self-extracting archives. When the program uninstall, it did not restore the default association for Zip files. As a result, I can no longer unzip files!
In most cases, you can restore associations by selecting open and the picking the program you want to associate with that file type. Unfortunately for you, the Windows zip file is not a program, but a shell extension. If you type in a command line:
ftype | more
You will see an entry for CompressFolder and it calls a shell extension dll.
To restore the functionality, you need to do the following:
- Select the Start Menu, select Start->Accessories. Right click on the Command Prompt and select Run As Admin. You need to be admin to change the association. You will be prompted to enter your admin password. Enter it and press return.
- In the command line window, type in the following command
Now when you right-click on a zip file, you should see the familar extract menu again.
