Grouping files by name will cause zsDuplicateHunter to group any files that have identical filenames together. Grouping by filename alone will NOT ensure that the files are unique. However, it is useful for finding extra copies of a file. For example, using a name comparison only will allow you to find backup files that have been created and forgotten, or to find songs that may exist on multiple CDs. When searching for true duplicates (using checksum or digest grouping), grouping by name can help to make duplicate files easier to manage.
