Adobe Illustrator keeps saving multiple files of a file I keep resaving?

[#1]

Every time I have saved a file on ai after I make changes to a file, lately it creates multiple new files rather than just resaving the original file under the same name. For instance, if my file was named "JoeShmo_NewPckgDesign.ai" and I saved it 3 different times throughout the day, it will not override this same file and save it with the new changes under this name. Instead, three completely new files called "JoeShmo_NewPckgDesign 1.ai," "JoeShmo_NewPckgDesign 2.ai," and "JoeShmo_NewPckgDesign 3.ai" show up on my desktop....? Therefore the file with the highest number becomes the latest edition, rather than the actual one I am working on in ai. This is making me unsure which files I should be deleting. How do I stop this from happening? I am running out of storage on my computer and this new feature is NOT helping....

Which version and system is it?

Exactly where do you save your files?

Do you have any autosave extensions running?

It does the same thing to me. If I have a storyboard I designed thats 250mb and I make revisions 3 times and save... I have multiple files that adds up to 750mb on both my computer and cloud.

Can you please answer the questions I posted above?

Im running the latest system on a brand new macbook. It didnt matter where I saved it because it did it regardless. Turns out, after I did an update on adobe, it changed something on my preferences. So what has to happen is you need to quit and restart AI, go to preferences / general then click reset preferences in the bottom right. That should solve the problem.... 15 gigs later...
