What really are the "things" that can "build-up" in the c drive?

I was just wonderin, what really are those things that can starts to "grows-up" and can fills up the C drive where our operating system was installed everytime we starts our pc?

I regularly use CleanCache 3, EasyCleaner v2, Registry Mechanic 6 and TuneUp Utilities 2007 to clean up and erase those tmp, chk, logs files etc...that can fill my c drive, but still I am curious if there's anything yet that needs to be manually deleted in order to freed up the drive for those unneeded and useless junkies in there.

Are the cleaners I've mentioned above enough for maintaining the "cleanliness" of my C drive? ...what are the things that we should regularly and manually deleted that those cleaners could not find?

 

Hello,

After you uninstall programs, they could leave leftover files and logs.
Updates to programs also inflate them, like AV databases, for example.
Temporary files and logs, as you mentioned them.

Here's a nice little tool you might appreciate:
