It may depend upon how it figures a GB. Some people call a GB<br />
1,000,000,000 bytes<br />
Others call it &nbsp;its binary result of 1024(1k) raised to the third power<br />
1,073,741,824<br />
<br />
This could cause the issue.<br />
<br />

<div>
you can check how it reports the disk size - that will show how it calculates
</div>


<div>
run windirstat as an administrator you will find the missing bytes. A standard user doesn't have access to all file locations. i.e. System Volume Information.
</div>


<div>
Yes - but the thing is that WinDirStat reports LESS bytes than explorer!<br />
<br />
I still haven't find what is wrong with this!
</div>


<div>
and what disk size is reported?? &nbsp; i Always have to ask things a couple of times on EE it seems
</div>


<div>
Explorer: 84 GB<br />
WinDirStat: 67 GB<br />
<br />
Difference is ~20 GB is too much<br />
<br />
I haven't found anything suspicious, like large files etc in WinDirStat. - In it, disk useage is completely normal, and what it should be.
</div>


<div>
mrmut &nbsp;- &nbsp;again : what disk size is reported - and what disk model do you have ?
</div>


<div>
OK, here you are:<br />
<br />
Type: INTEL SSDSC2BW120H6<br />
<br />
Reported capacity: 104 GB<br />
<br />
Explorer used:<br />
85.9 GB<br />
<br />
WinDirStat:<br />
67.7 GB
</div>


Showing the difference between run as administrator and run as a user

<div>
so you have an SSD of 120 GB and windows report it as 104 GB<br />
then it's no wonder the other figures are too low also<br />
<br />
do the calculation sstory asked in his first post - &nbsp;and tell us what you find
</div>


<div>
The computer user is local computer administrator, and the disk size is fine, as it also contains two computer restoration hidden partitions from Lenovo.<br />
<br />
I will, however, check results with WinDirStat run explicitly in administrator mode, and report back.<br />
<br />
Thanks.

<div>
Eureka!<br />
<br />
It turned around that RRBackup folders were taking the additional space. I didn't see them with any tool, except when using TreeSize Free.<br />
<br />
So, I deleted the old backups, and voila. The free space is back.

I have a weird problem in several clients on Widnows 7 x64.<br />
<br />
Their computers show wrong disk usage.<br />
<br />
For ecample - when viewed from explorer, C: is shown as occupying 84 GB, and when I scan all files with WinDirStat, it shows 67 GB.<br />
<br />
Can anyone help? :)
