There are two different values, the sum of all file sizes and the
allocated disk size.

You can calculate this values with FindFirst, FindNext, ... To
calculate the second value, you must the file sizes align on cluster
size. The determination of cluster size is difficult for a FAT32
Partition. I have write a demo program to calculate both values for a
path inclusive determination of cluster size for all disk types. I
have test the program with FAT16, FAT32, NTFS, CDFS under Win98SE and
Win2k.
