C drive 95% full, but if I ctrl All and right click to see total size of all files...only 20/75GB used?

It says I only have 3.64/74.4GB of space left on HD. I ran cc cleaner and reinitialized the cache and deleted old user accounts, still barley any room left. So, I open up the C: drive and do a Ctrl+All and right click to see total file size, and only 21GB being used in the whole C: drive!

What is useing up so much damn space!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What does this have to do with Excel?! Wrong Zone perhaps?

Folder OptionsView tab > enable Show hidden files and folders and uncheck Hide protected operating system files (Recommended).

You should now be able to see other folders for which you can perform the Select All and then right-click for Properties.

Did you empty your trash?  When you delete things, they are simply saved in a different place until you want to recall them.
There are also different reporting mechanisms so sometimes the numbers you see are not the same (although usually only 1-2% difference.)

Also, you don't need to use Ctrl-A to check the size.  That will only give you the size of the selected files (so you'd need to unhide.)
Instead, de-select all, right-click on the drive letter in the folders panel, and select Properties.  That will tell you about the C-Drive rather than the selected files.
Empty Recycle Bin?
Also check how much System Restore is using, and flush it.

Don't open the the c: drive go to my computer and right click c: drive and go to properties. Then you will see everything inside including hidden files. When hidden files are not shown even if you select everything the hidden files won't be selected.

To show hidden files refer to yobri's instructions
There are a lot of things that take up space on the C Drive that you cant see unless you choose to show it. As mentioned, Show hidden files and also show system files, that will give you more of an accurate reading but I dont believe that includes System Restore or Virtual Memory or any of that. I could be wrong though.
there is a program called treesize which wil show you the used space by files and foldes. There is a free version available.
That won't show you how much is being used towards system restore though right?
