Is deleting files on the temp folder harmful?

[xxxMoRaVexxx]

Hi, I'm not much of a computer software guy(I'm more on hardware). Ok here's the prob; I recently installed a windows XP which I borrowed from a guy. It has many pre-installed stuff that comes from the installer like a .pdf reader, 7zip, Codec pack, etc, etc. I was just looking and digging up its folders then I found the temp folder which already has stuff inside... Just wondering if is it safe to delete everything there? Thanks in advance.

You have to mention the path where this temp folder resides but mostly it's safe.

Not a good thing some TEMPS are very useful for your backup DX files or sometimes temps can be earlier versions of your OS these files sometimes are critical deleting will give you further complications as above said GRRR you need to state your given path and your main path folders the ones you want to remove !.
