'Previous Systems' folder?

[eyeon]

When I first got my Mac in August, it had some problems. I was on and off the phone with Apple tech support for a good month before we fixed the issue. Now, everything's fine, but I have a folder on my primary HD called "previous systems" and I can't remember if it was there before or not. The folder's contents add up to like 2 or 3 gigs, and I am nervous to just delete it, but wonder if I need it. It has a full lineup of recognizable folders, like Applications, Library, etc, as if it is a backup of some sort. Is this a normal nessesary thing to have on a Mac HD?

Thanks in advance.

The Previous Systems folder is created when you do an archive and install of the operating system. The old system is copied into this folder, and then the new one is installed. If your new system is working fine, then there's no need to keep it.

Duff-Man says...as HexMonkey says, that is indeed created from an "archive and install." What I usually do with that previous system is wait a bit...try out all my apps and make sure they all work fine...when I am satisfied all is well I delete the previous system folder. If you've been running okay since august I think it is a pretty safe bet that you can delete it now...the worst that will happen is that there will be some obscure app you have not used yet that may need to be re-installed....oh yeah!
