calc.exe. There are 512 bytes to a block. You can do the math in your head after the first coupla times, because 1K is two blocks. The problem comes in the way that a 12 byte file will appear in Windows as a 1Kb file, because Windows won't measure in less than 1K increments. So there is some accuracy loss there. A 1 block file is a 1K Windows file, but so is a 2 block file! The workaround is the fact that you're usually measuring in larger (1M+) numbers, and can afford to round up to the next largest Kilobyte. >I'm trying to find a program (Windows or Linux based) that will >calculate block size into KB and/or MB for a couple of our new >Windows admins to configure disk quotas correctly on linux servers, >since it's going by block size instead of MB or KB.  Anyone have any >suggestions?
