Space On Hard Drive

I have 80GB hard drive (yes I know it's puny) on my computer. I only have 31GB free space. My total size is 74.5GB. So I'm assuming the 5.5 is made up of programs needed to run the computer etc.
I have deleted all my music video and audio files/folders which were taking up even more space. I've tried defragmentation, emptying the recycle bin etc etc. I've uninstalled some rarely used programs.
In my Program Files there are 49 Items taking up 34.3GB of space. Surely this is too much ?
I do have Nero and Roxio which take a lot of space.
Looking at 'Control Panel' I see 'Microsoft .NET Framework 1.1', 'Microsoft .NET Framework 2.0 Service Pack 2' and also 'Microsoft .NET Framework 3.0 Service Pack 2'.
Do I really need 1.1 and 2.0 if I have 3.0 ?

 

the difference between 80GB and 74.5GB is down to one being a Decimal figure and the other a Binary figure.
80GB = Decimal
74.5GB = Binary
there is NOTHING taking up 5.5GB of space as your assuming, there is NO 5.5GB of missing space.

 

OK but what about the rest of my querie ? What could be taking up all that space on my HD ?

 

Go to start> search> type in c> search, this lists what is on the drive

 

Run TreeSize to see what's taking up space.

 

How much disk space do you have allocated to System Restore?
What percentage of disk space is used for Recycle Bin?
Is Hibernate enabled?

Have you set your folder options to show hidden and protected OS files?

Have you run a cleaner program such as CCleaner? (NOT registry cleaning!!)

You may have lots of HotFix Uninstaller files taking up a lot of space too... CCleaner has an option to remove these

 

Did what you said. The result was 'Search Complete - There are no results to display' Typed in c>, got nothing, then typed in c>search, still got nothing.

 

Windows Temp folder had only 108KB in it so wouldn't save much there. Besides, Windows wouldn't let me delete everything in the folder as some files were 'being used by another person or program'.
Couldn't find C:\Documents And Settings\(Username)\Local Settings\Temp
On my computer I have Documents and Settings then 'All Users' and 'Owner'. I don't see Local Settings anywhere.

 

Didn't like the warning I got from Windows when I tried uncheck the box to show hidden and protected OS files. Are you sure about this ? Why the warning if it's OK to do what you suggest ?
Hibernate ? Don't know what your talking about.

 

There are still unanswered questions from my first post. The last time my 80GB hard drive was almost completely used up I deleted everything I could. This brought me down to approx 65GB free space. This time, I deleted everything I could think of, did all the same things as before but now I have only approx 40GB free space. WHY ?

 

YES, I am sure
If you allow the showing of the hidden and protected OS files you would see "C:\Documents And Settings\(Username)\Local Settings\Temp" folder

Go to Control Panel > Power Options
click on the Hibernate tab
is it enabled or not?


Have you run CCleaner yet??
there are plenty of tutorials online if you care to look its a very easy program to use.

How much space is taken up by HotFix Uninstallers? ie these $NTUninstallKB*****$ in your Windows folder?

 

There is nothing to delete in the Temp folders. I've checked those.
Hibernate is NOT enabled.
HotFix Uninstallers in Add and Remove Programs - HotFix for Windows XP, 7 of
HotFix for Windows Media Format 11, 2 of.
In Windows folder there 110 $NTUninstall thingies.
With regards to CC Cleaner. What boxes do I check and/or uncheck ?
