Determine Wasted Space without FAT 32

Want to know how much space you have wasted since you do not want to convert your old FAT 16 to FAT 32?.

Click Start, Programs, MS-DOS Prompt. At the DOS prompt, type cd\ and press Enter. Now type dir /a/s/v and press Enter. The difference between the value for Bytes and the value for Bytes Allocated is the amount of space not used by the files, but allocated to the clusters that store those flies. Subtract Bytes from Bytes Allocated to determine your wasted space.
