solution to explorer.exe using too much memory

Hi all.After doing a lot of research and thinking I have found out an easy way to drop the amount of memory which explorer.exe uses.For days I scanned my PC for viruses malwares and found out that it was clean.I had booted up with explorer.exe 60.000 and while I worked it went up to 88.000, but the CPU usage was only %2.
Solution: my documents folder contained a lot.My pictures and my music was under my documents,I moved them under C:\WINDOWS and also moved some of my docs to a removable media.My docs was 114MB now 12MB.And a miracle happened.Now I boot up with explorer.exe 27.000 and go up to 35.000.I hope this helps some of you.
