Re-associating Compressed Folders with .zip files
Once upon a time I installed WinZip and so the .zip file association got switched to WinZip. I really like selecting files and then right clicking and selecting Send To > Compressed (zipped) Folder in XP/2003. However you cannot do that unless Compressed Folder is the program associated with .zip files. It will usually ask you "Do you want to designate Compressed (zipped) Folders as the application for handling ZIP files?" and I always click yes but it never re-associates. Anyways I found a registry fix on Doug Knox's page Windows XP File Association Fixes. If you import the ZIP Folder Association Fix into the registry it will restore the default .zip file association. Now I can use the Send To > Compressed Folder again. Thanks Doug.
On a side note at one point the Compressed (zipped) Folder was not even an option in the Send To menu. So I tried to figure out how to put it back. I looked up and down through the registry only to figure out later that the Send To items are stored as shortcuts in a Send To hidden system folder in your profile. If you need to add it back the easiest way is to copy the Compressed (zipped) Folder shortcut from another profile into your profile.
