Hard Drive filling up - Windows 7

[Lloyd Thrower]

I have Win7 installed on a 250GB solid state drive. It keeps filling entirely. Not a Chkdsk issue. Not a Restore point issue. Installed TreeSpace and saw a lot, but not sure what it all means. Most space is used up by 1) Windows itself (149GB), and 2) Users (68GB). Under Windows "Temp"is the biggest culprit - 75.5GB - which seems ridiculous. Hundreds of cab files, mostly all 122.2MB. Also lots of Windows.net Framework text files, many pretty large. Do these files do anything? If not, why do they pile up like this? Can I erase them? Under Users it appears iTunes is a problem. Over 20GB of mobile device backup files. I've deleted all of those with seemingly no impact. In general it appears that even when I install programs on my D: drive, a lot of related files end up on C:. Any way to avoid that?

you can deleete you temp fies.. that folder is pretty much stuff you downloaded useless junk about 98% of the time if you run a disc clean up you can browse through it

to fix that issue me personally i have more than 1 hard drive in my computers

my first hard drive is for my OS
second one is for games
and a 3rd one for back up

id buy a another hard drive dude( main reason why windows sucks is the disk space it takes)

another thing you can do is use a linux based OS there only like 400 to 600MB

Before you delete files by hand (which can leave debris pointing to stuff you deleted) try this:

Right click the disk drive in file explorer
click properties
click disk clean up
<it will pause a minute while it calculates how much you will save>
click the 'clean up system files' button
<it will pause for more calculations>
go through the check list and check all the things you are willing to delete, make sure you get any dump files. etc.

Good Luck.

OCD Tweaker,
I actually have several hard drives in addition to the solid state drive - and internal 2TB and several externals. I theoretically use the SSD only for the OS and a few basic tools (iTunes and Browser). That's why this was perplexing to me. The 75GB in Temp still boggles my mind. There are several hundred that have file names like "cab_10872_2" (numbers vary) and are exactly 122.2MB. Are these truly useless and can be deleted? Why would my OS save all these anyway? Many others that are also quite large have file names like "Microsoft .NET Framework 4.5.1 Setup_20140226_030041297-MSI_netfx_Full_GDR_x64.msi.txt" (again numbers vary). Are these equally as useless and can be deleted?

These are the files that allow you to roll back MS shipped Windows updates.

They are also the files that are deleted when you use "disk clean up" with the system files option and check the right boxes.
