Since I now use Free AOL in MSIE, I'd like to know if it's safe to delete all AOL files from the C:\Programs Files\Common Files directory, since I've uninstalled AOL software. These are the folders displayed:

AOL
aolback
AolCoach

The contents of these folders take up considerable space. My system is Windows XP Home, HP Pavilion 750n, CD-RW & CDRom, service pack 3, 736 MB Ram, 4 pentium, 1.60 Ghz, DSL, Internet Explorer 8.

Thanks for help.
