This morning while looking for something else, I discovered a folder on my external drive that had my name on it but couldn't remember what was in it. So I opened it to see and saw backup files, which I presume were for my OS (they are in Zip files). I counted and there was 32 backup folders of files-starting with the oldest being August 2008. I also have a backup program for my browser, Firefox, but I knew that these files were not those because I only recently started using that program. Can I safely delete most of the files? And if so, how many should I keep? Is there any way to configure so that you don't accumulate so many backup files--and if so, where would you do this and how many would you tell the program to save?
Thanks,
Sheila
