Does that means i really don't have 2.95 GB free? Does windows 7 somehow use compression even though i tell it not to? I do have show all files enabled btw
The properties of the C drive are correct in what it tells you. When reviewing file size by going though folder properties, a lot of the files are counted multiple times. This is because of folder junctions and hardlinks. The drive properties however, does its calculation of space by examining the bitmap which is by far the most accurate.
Hmm, that explanation is the best one so far. But still strange. It just strange because i haven't seen this behavior of files counted multiple times due to folder junctions and hardlinks in XP. Is this something different in win 7?

If you don't use Hibernation, you can probably free up another gig by making sure Hibernation is disabled and deleting the hibrfile.sys

Where does the drive space go? When going to use a 16gb flash drive some 15.04gb will be found available there. The image here shows 142+gb of data including the 7 installation itself deducted from a 1tb drive.

For the 10.2gb C you have there before adding anything on it you should be seeing some 9.49949026107788gb according to one hard drive calculator seen at The Tomorrow Times: The Hard Drive Capacity Calculator

To convert decimal units of measurement as drives are labeled into binary units of measurement to see where the drive space goes you can thank Airbot for the best multiplier of 0.9313226 multiplied by each gigabyte of hard drive space.

Besides having the paging file created on D one other factor not mentioned is what? system restore points

You will get the most accurate reading (as far as I know) of your hard drive space and files on it by using a one of couple apps I like.....

WinDirStat Portable | PortableApps.com - Portable software for USB drives

freshney.org :: Xinorbis

I don't have an answer for the original question though.

I am not sure if most people understand what i am saying yet. On that box that Night Hawk shows for drive C property, mine would say the used space is 7.27 GB and free space is 2.95 GB and total capacity of 10.2 GB. But if i manually highlight all the files and folders on drive C and right click and select property, it would say that there are like 65k files and a few hundred folders and they use 9.81 GB total.

Does anyone see that this does not jive? the used space stated in the drive c property box should equal to the total space that all my files and folders use unless like Logicearth said before that some files are being counted more than once somehow.

I probably will make a screen capture to clarify....

i did have restore point and hibernation disable. And I am not talking about converting between binary and decimal definition of GB.... The number mentioned in my posts are all binary GB.

Don't disable system restore - it is essential, configure it so it takes the minimum space required.

I do understand what you are saying,,,, and I am sure there is a logical explanation of it.

When looking at the properties of all files on C: are you looking at Size on Disk or Size?
I think Size on Disk should correlate with Local C: Properties Used Space.

The screen posted earlier is in binary there as well being looked in Windows. That comes out to an even figure with the "Hidden system files" options unchecked in the menu bar>tools>folder options>view tab.

The files unaccounted for there would be those if you left everything at the default view settings and be one explaination right off for not adding those into the total.

here's my screenshot. I did this for all my other drives and they all make sense except for C drive.

there should be a simple explanation....
