For some time, every time I create a new file on my MacBook using Microsoft software that I save to my Dropbox, the computer automatically creates the file (e.g. a document) and a separate folder with a backup copy of the file created. It's annoying, creates clutter, and probably uses extra memory.
How can I stop this so I can just save one copy of the file? It used to work like that for a long time. The other question is whether there is a way to delete the unnecessary backup files automatically. Thank you!
