Calculate optimal disk cluster size with Cluster Size Calculator! Cluster Size Calc allows you to scan files and folders and compare their efficiency in a variety of [[data cluster]] sizes. This works great if you have a folder (and subfolders) of files that will be moved to a new drive. It will help you determine what cluster size to use on that HDD in order to use the least amount of clusters (indexes), and waste the least amount of space.
For many of us with collections of pictures, audio, and video, the commonly chosen cluster size (or even default) is not the prime cluster size. This utility helps you figure out what is right for you.
Calculates clusters sized from 512 bytes to 32 MB – the cluster sizes in FAT, NTFS, and exFAT.
This program is considered ‘portable’. Just download it and run it, no installation is required. However the systems that run it will require at least 2.0 of the .NET Framework (if you have XP or Vista or 7 you likely have this).
