DiskSizes 1.0 shows status information about your computer´s drives. This information includes cluster size, free space and total size. Files are stored in an integral number of clusters (or allocation units). This information may be useful when you are storing a large number of small files.

Also measures a folder´s disk use and displays the number of folders, number of files and sum of the file sizes. This total disk use may be relative to the cluster size on any of your computer´s drives. This information may be useful when you are copying or moving a folder.
