Vista - Cleaning Up Appdata Folder + Where Is My Free Space?

[lesliebibb]

I'm cleaning up my 50 GB C: drive but I'm having some issues:

 

1 When I go to C: and "select all" (including hidden folders), it says I use 35 GB. According to windows my drive is 45 GB, but it says I have 2 GB free. So what about the 8 GB difference?

 

2 I found out most of my space is in c:\programdata and users\appdata. Is there a way to auto-clear out these folders? If not, windows sucks because everyone has this folder!

 

I'm already using ccleaner.

 

Thanks!

How much is stored in 'system restore'? http://ask-leo.com/how_do_i_get_system_restore_to_take_up_less_space.html

System restore only has 2 items, yesterday and the day before. I always keep that low.
