I'm running windows server 2003 R2, used as my file server. The total size of my C: is 7.81 GB w/ 24MB of free space. I need to increase my free space. I have run Disk Cleanup and there is 2.6GB of Temporary Files, can i delete these files w/o creating problems. I have already deleted the temporary internet files. I'm not sure what these Temporary files are.
