I have windows 7 professional 64 bit and ran Windows disk clean-up to see how much disk space I could free up.
I was surprised that windows 7 reported that it could free up 326 GB of disk space by removing temporary files alone (not temporary internet files).
Exactly what doe disk clean-up consider to be temporary files and is there any possibility that performing this clean-up could introduce any problems or loss of meaningful data ?
The disk is a solid state 939 GB disk formatted with NTFS and currently has 640GB of used space.
I have made a restore point but I imagine restoration wouldn't reverse the disk clean-up ?
