I keep getting low disk space. I have 2 hard drives one is the C drive the other is the E drive.

C drive Total Size 9.30 GB
C drive Free Space is currrently 189 MB I can get this up to somewhere in the high 200's by doing Disk Clean-up. That seems to be the most free space I can get. I have very little on my computer, however I do have AOL, I have been told that this takes up a lot of space. I would like to keep AOL is there any way I can delete some of it that I don't need. Also maybe there are other things I can delete to give more space, can you tell me what things I can safely delete to get more disk space on my C drive

E drive Total Size 18.6 GB
E drive Free Space 17.6

Microsoft Windows XP
Home Edition
Version 2002
Service Pack 3
Intel Pentium III Processor
930 MHz , 288 MB of RAM

Thank you in advance for any information you can give me.
