My hard drive partition has 323GB of total space and 154 GB of it is used by my files and pagefile.sys, So doing math, 323 GB - 154 GB = 169 GB, BUT the free space on my hard drive is shown as 110 GB which makes a deficit of exactly 59 GB. Can anyone please explain me what is happening here. I am attaching an image which shows the calculated size and the size of my drive as well as the size of all the files in this particular partition.
Not everything shows up in explorer. Common examples are:
As yours seems not to be the system drive, my guess is for the recycle bin.
If you want to see the full disk usage, open the properties of the disk, rather than selecting all files and opening the combined properties: note on my image that "All in C." to the right is not the same as "used space" on disk C:\
Also, a tool like spacesniffer (in the background on my image) can help you to see everything that's on your disk and analyze "where all that space went" :).
