Re: [WIN] drive space used != total file space used; whynot?
Vern,
Ok, I understood the difference between what the size of an individual file
is and the amount of space taken up on a drive by that file due to unit
cluster size, and have accommodated that clumsily (still haven't found a way
to programmatically discern cluster size); I was using the "properties"
comparison originally to see if my code was correctly handling cluster size
increments and summing individual directories size used correctly, so I
thought to do the same for the drive as a whole, but I'll probably take your
advice and ignore it. Thanks.
Dan
