I still have a folder called "System Folder" that belongs to the Classic environment. It takes up almost 400MB on my disk. Since I'm running Lion, can I safely delete the entire folder?

Wow, you still have that?! You must have transferred all of your data from machine to machine. Sometime, you might want to consider a complete reinstall to remove any other oddities that might be lying around. – Jamie Aug 6 '11 at 0:31

Considering the Classic environment was phased out versions ago, I think it would be completely safe to delete a folder belonging to the classic environment.

It's probably safe to delete it, unless you're like me. For example, I still keep a directory of pictures in the Appearance directory that I use for wallpaper. Old habits die hard. :-) You might want to check if you have anything similarly quirky.

Absolutely. Everything equivalent that Lion needs resides in the new "System" folder (and others) so you can freely delete your old System Folder.

I did a clean install of Lion and there is no "/System Folder/" there, therefore I believe that you can safely delete the folder "/System Folder/" however make sure you do not delete the "/System/" folder, otherwise you'll be left with an unbootable system.

(Of course you have a working backup, right ;-?)

Working backup and Carbonite backup. (Been burned before.) – Bill Aug 8 '11 at 4:43
