Do I Clone or Sandbox?
 

I have run out of room on my 20G hard drive on my G4 desktop. I cannot install any more applications and I've already removed almost all files that are not applications. I've installed an additional 80G internal drive. I want to clone my original HD to the new one and use the new one as the start up disk. I thought I would then delete all files on the original HD and use as extra storage for files. But now I'm not sure if I should do that, after reading about Sandbox.
Can anyone suggest which is the better way to go? I assume if a create a Sandbox, I will have to leave the original HD information there.

Thanks.

Do a "Backup - all files". Don't create a Sandbox in this case.
