Hi Robert,
The "missing" 60 GB is not actually missing. Some system files and folders
are actually hidden to prevent accidental deletion, and if you choose to view
these you should find that you are able to account for this figure. These
include the page file (typically upto 3 times RAM), hibernation file (equal
to RAM), recycle bin (upto 10% of total drive capacity) and system restore
(again, upto 15% of disk capacity). Using these figures, if your hard drive
has a capacity of 250 GB and you have 2 GB of RAM installed, this adds up as
follows:
3 x 2 (page file) + 2 (hibernation file) + 250 x 10% (recycle bin) + 250 x
15% (system restore) = 55.5 GB
There are other files and folders which are hidden and which add up to the
other 4.5 GB, but this gives you an idea of the amount of space actually used
by these files and folders. You can easily change the amount of space
required by the page file, eliminate the hibernation file and change the
capacity of the recycle bin, but it is not easy to change the space
requirement of the system restore files except by editing the registry. If
you want, I can provide details to carry out any or all of these changes.
