My Mac Mini storage says it's almost full but it seems it is not... I need help
I don't really understand what is happening, I have a Mac Mini Late 2014, 1tb hard disk. It has 3 profiles, but I only use one of them. I clicked on "get info" on these 3 profile folders, there was 400GB in my profile and the other 2 had 0-5 GB storaged on both. But when I opened the app "About this Mac" it said that there was 240GB on "other users". I thought that was impossible then. Someone know why it says it has so much storaged there? Can I somehow delete that all?
I also have another question, on "About this Mac" I have also found out that I have almost 120GB on ''Documents", but my documents folder has only 10GB. All of this is making me so confused, can someone help me?
Mac mini, macOS 10.15
