Cluster Size Calculator allows you to scan files and folders and compare their efficiency in a variety of [[data cluster]] sizes. Calculate optimal disk cluster size with Cluster Size Calculator. 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.
