Grouping by Size

Top   Previous   Next

Grouping files by size will cause zsDuplicateHunter to group any files that have the same size (measured in bytes). Grouping by size alone will not determine if files are true duplicates. However, grouping by size can help you to determine which duplicates you should concentrate on. Duplicates that are very large will save the most space on your hard disk if they are removed. Zero size files can be safely deleted in most cases. These files do not take up much space, but they can slow down searching for files as well as backups.
