Windows 7: windows 7 still eating disk space

Windows 7 professional

for Win7User512:
that's an original idea!!!! EXCELLENT!!! PROBLEM SOLVED!!!!

sorry for the irony but.... LOL we can say SOLVED to all problems on this forum!!! The final solution!!!

i have no time for reinstall all programs i have, and the system is fine!
I was just thinking now that maybe the cause of this eating can be the fact that in the last days my pc reset himself i think for hardware issues, and maybe there are files of logs and error report that win7 create for that, but in this case i dont know how locate and how to cancel these hypothetical files
Someone know the answer?

Hi darmok47

What win7user512 suggested is probably the best solution given your existing issues.
It could be that your installation is corrupted - something gone rogue etc. or at worst, your PC is a bot
Unless of course you prefer to leave things as they are.
Whatever the outcome, you are going to have to find the time to reinstall some time soon.

Hope this helps in your decision

Windows 7 64bit

Justo say, I have same problem on my Win 7 64bit.
I have also turned off everything that could eat space by itself and my pagefile is on other hard drive, on its partition (I have three HDDs: on first are system partition and two for work. On second is backup partition and pagefile partition. On third is ubuntu linux)

My system partition is only 20GB large and it is good because win7 and all main programs and applications take max 15GB. So 5GB is just to sit there untouched...
but it isn't the case: I keep loosing space by itself and I cant see where it is going!
I used all kind of space explorers, and just for example "TreeSize" app says I'm using 15,331 MB but in explorer it says I have only 2GB free, so 3GB are mystically "gone"
I've noticed that when PC is not doing anythig, it looses about 2MB every 3-4sec

Just as intresting thing:
I'm using flashget download manager installed on system partition and when it is downloading files on other partitions, i also loose space on system partition. It looses space with ratio 1:1 so if I download files that goes more that 5GB, system partition will be filled to the max...
But the intresting thing is that when I exit from flashget, space just appears!
So I've installed it onto another partition and now I dont have problems with it...

As I've come to conclusion, problem has something to do with windows protection of "program files" folder on system partition, where it looks like that win doesn't allow programs to write anything into the "program files" by themself, but allows them to write into the system partition like unregistered data that will be lost once program doesn't need it...

I've decided to try this theory by reinstalling all the applications onto the other partition, and let the system partition be only and only for windows...

W7 64 Bit

Download CCLeaner and be sure to run it in Default Mode. This will delete index.dat files and tons of temp files in your system. I am not keen on Registry Cleaners unless the user is an Advanced User. You need to know what to choose to ignore and what to allow the registry cleaner to repair. If you are knowlegeable in this area, then take advantage of CCLeaner's Registry Repair feature as well. (make a system restore point before you install CCLeaner as well. I bet you have great results. Please report back. You can cownload CCleaner from under Downloads/Windows

Win 7 Pro

Hi there,

I run Win 7 Pro on a Thinkpad T510i (received a few weeks ago) with a 300 Go. Deducing the 15 Go of the recovery partition, I still have around 285 Go for my OS and files. My files and programs take about 150 Go. However, the Win Explorer "tells" me that only 20 Go are available on my disk. So I lost about 100 Go somewhere (over the rainbow?)...

I tried cleaning files, useless softwares, spywares..but nothing changes ! I read something about indexing options (that could consume a lot of space if indexing is activated for all your files) but I don't know if changing these parameters will allow me to recover the "lost space"...

Does anybody have some news concerning this problem. I think that this is not a virus problem but clearly a Win 7 problem (I found lots of testimonials of similar problems...).

Thank you in advance.
