Free disk sapce in C:

I have Windows Xp in my other computer and I Install Symantec Sweep and clean, this program when is open presents 2 lines one blue and one green, the green is the space tht I can clean, and when this are clean the blue is a solid line. OK. I don't know what I can do to clean this but I try and try and I do nothing. I go to propertis in my browser and delete all and viw files and deleted, I open clean and sweep and in there delete all, I clean all to a empty file. But when I open fast clean, and do the clean things, the blue line still broken and the green have "space to free ". I hope you have a solution to me and please excuse my bat english, I try to type and spell correct, sorry

 

There are some files that cannot be worked on while XP is running.

Unless it is causing you problems, I would ignore it.

You can deal with some of the files (pagefile & registry hives) with a free program from www.sysinternals.com called pagefiledefrag (or something similar). It will defrag these files before XP loads.
