Hello all,
The bootable D drive in my PC is a 16.9 GB (formatted) SCSI. There are
only 3 folders on it that contain data: Documents and Settings (1.37
GB used), Program Files (1.03 GB used) and Windows (3.34 GB used). I
obtained these figures using folder properties. The sum is 5.74 GB.
When I select drive properties, Windows reports 7.68 GB are used -- a
difference of 1.94 GB. Quite a big difference.
Thinking that the disparity might be explained by hidden or system
files I scanned everything on the drive with a directory command (dir /
a:r /a:a /a:s /a:h /a:d *.* /s) ... and got exactly the same figure
reported by drive properties!
Kudos to the person who explains where 1.94 GB is being sucked up.
On average a stored file appears to waste half the cluster size. If we
assume that the cluster size is 4k bytes (that is storage is allocted in 4k
blocks), then a 1 byte or a 4096 byte file will use 4k of disc space. A
4097 byte file will use 8k of space as an extra 4k cluster has to be
allocated. If your folders contain a total of 9500 files then each file
wastes 2k of storage on average and this works out to around the 1.94 Gb
that you think you have mislaid.
