Re: 32MB is size???

["Jack Tseng" <tseng4@hotmail.com>]

Linards,

For example, 256 bytes times 65536 equals to 16,777,216 bytes total ~ 16MB.
Another example of Microsoft FAT16, 32,000 Cluster Size times 65536 equals 
to ~ 2GB.

Is it 256 bytes times "double 65536" equals to 32MB ? or 512 bytes times 
65536 equals to 32MB or ??? bytes times ????? equals to 32MB.

Is it clear?
Thanks!
Jack
