Grouping by Extension

Top   Previous   Next

Grouping by extension will cause zsDuplicateHunter to group any files that have the same extensions together. Grouping by path alone will NOT ensure that the files are unique.

 

This option is useful because it separates files according to the type of a file. For example, using this option will separate jpg files from gif files and png files. This option can also be useful to separate backup files from original files. For example, some programs will name backup files with bak for the extension or with a tilde and the original extension. Using this option would ensure that the original file and the backup file were not grouped together.

Grouping by Extension is available in the Professional Edition only.
