unable to save your computer will not let you save files

i still get the same popup. all i wanted to do was change the category of an item. not sure what im doing wrong first time user.

Google says it's a permissions issue. The location you're saving to is either a folder set to "read only" or a folder you don't have administrative access to. Saving to a location such as an alternate drive or the desktop should bypass the permissions problem. You can also try running Studio as an administrator.

This thread is for Word document issues but the same principle applies. It talks about having a long file path, i.e. your file located in a folder that's in a folder, that's in another folder, and so on. It also talks about Windows trying to save to the cloud (your One Drive account) in addition to saving it to your local machine. You can set Windows so that it's not synced to the cloud anymore. Of course, I'm assuming you're on Windows.
