When I right-click on a folder I want to compress, then right-click > Send To > Compressed (zipped) Folder, it just starts compressing. It doesn't go through the normal process of asking me what the folder should be called as it usually does, and I don't know where the zipped folder is it's sending to...
How can I make it behave normally again?
The short explanation: I needed to refresh the File Explorer Window (Right-click empty space > Refresh).
The long version: Windows was creating the zip folders in the folder I was in, but wasn't showing any of them.
When I opened a new File Explorer Window, and went to the same folder, all the zipped folders were there (I tried to zip the folder a few times to make sure I wasn't crazy). It might be a setting I or my sysadmin set and forgot about because it doesn't do that on my other computer.
I'm not sure when this changed. In the past when I have zipped a folder, it asks where to put the zipped folder, and it shows up immediately.
