Weird folder on Time Machine disk

[Mikel30]

I have a hard drive that I use for Time Machine and that is the only thing I've used it for. So when I open it, there is a Backups.backupdb folder. Well I just connected my hard drive and I browsed through it. Instead of the just the Backups.backupdb folder, there is also a folder called "private". If you open that folder it goes private -> tmp -> tempVM -> vm -> swapfile0. I have no idea what it is. I tried googling it and the only thing I found out is that it sometimes pops up if you use it to restore a computer (which I recently did). It looks like it's supposed to be a hidden folder but I couldn't find anything about correcting the problem. Any ideas?

I installed a new hard drive in my macbook and used a time machine restore to put my data on the hard drive. For some reason, I got the "private" folder on my backup drive. It's 64 MB and has only one (visible) file in it (/Volumes/Time Machine Backup Drive/private/tmp/tempVM/vm/swapfile0).
Can I safely delete this file? Thanks.

If its on your time machine drive, why don't you just leave it? I don't know about you, but i rarely if ever look around at stuff on that drive, it just use time machine. And 64MB isn't that big if you're worried about the space.
