How to un-assign the file extension ? RRS feed

  • Question

  • I find Vista handicap in this arrangement. I can associate an extension with a program. But if I did it wrongly, I cannot un-assign the association to none in the Control Panel - Default Programs - Associate File Extension. What should I do?

  • Thanks for your suggestion, although it is useless!

    I asked "un-assign" not "re-assign". For example, I accidentially assigned ".001" to WinZip, but I found it should not be associated with any program. How can I restore that file extension back in its initial state, i.e. assign to no program?

    you can try to del the assocatied registry as follow

     

    1. Run "regedit"

    2. Registry "HKEY_CLASSES_ROOT" e.g. is .001

    3. del the ".001" folder

     

    Note

    Before del the associated registry, Please export the registry for backup

  • With Vista, you can only associate file types, but you cannot unassociate a file type directly.

     

    In order to remove a user-specific file type association in Windows Vista, you can use a freeware called Unassoc (v1.3) for Windows Vista.
