I have Access 2016 and a file I've used for many years. I sometimes will do a compact and repair on the file and it's always worked before. Yesterday when I tried, I got a message saying I couldn't compact and repair because the file was already is use. I'm the only user on my home computer. I worked with Microsoft tech support but they couldn't fix it. The file seems to work OK except for the compact issue. Also if I try to save a backup copy. Thanks for any help.
