With newer and updated versions of the software, a new company website file is created, and the old one stored with an old version number after it. I have about 11 copies of my website in the home screen. Of course I only open and work with the most current one. Is it okay to delete the really old copies and just keep the last 3 or 4? There is not any consequence with any important files that would be deleted when getting rid of an older version, right?

Thus the newest version has saved everything it needs separately, and does not look for any older files contained in older versions? I just do not want to delete old crap, and then find out I have missing picture files or missing any kind of files that I will not be able to retrieve.

Thanks,
