The above two items appear in my Disk Cleanup window, and I would question if it is o:k to delete them. The first occupies a space of 283 KB and the other 2537 KB. The description given of these two files in the Disk Cleanup window is "Files created by Windows". I have a second question: I have approx. 5 GB left as free space on my "C" Hard Drive. Is this considered sufficient or should I have more? I am a retired senior and only use the computer for basic items. I have a Dell Dimension 4100 Desktop computer with Windows XP - Home Edition Operating System - Service Pack 3, Pentium 111 with 930 MHZ, 20 GB Hard Drive and 512 MB of RAM. The file system is FAT 32. Many thanks for your co-operation and response.1 person got this answerI do too
