As I am a retired senior, I use my computer for basic items only. I have a Dell Dimension 4100 Desktop computer with 930 MHz Pentium III processor, 20 GB hard Drive and 512 MB Ram. Windows XP – Home edition Service Pack 3 is sunning in my system. I have seen Log files of size 2537 kb and dump files of size 283kb Disk Cleanup window. As these files are created by windows, I have a doubt whether to remove them or not. So I wanted to confirm whether it is fine if I delete those files. What are they actually? Help will be appreciated.
