Select specific duplicates

Question / Problem

TreeSize works great in finding thousands of duplicate files, but how can I select the subset I want to delete other than one at a time?

Answer / Solution

If you want to keep the newest file of every group only, you can select "Check all but newest" from the "Duplicate Files" tab in the ribbon menu. In addition to that, the dropdown selection offers a large variety of additonal options to custom select files.

If you want to choose for each group of files individually which one to preserve, you obviously need to do this one by one.
