Mark for Removal rules provide instructions for FolderMatch about which duplicate files you want to keep and which ones you want to mark/select for removal. You choose one of these rules and FolderMatch will mark the files that match the rule in each duplicate group.

 

You can select a rule from two locations on the Find Duplicate Files window:

 

1.The Mark button on the main toolbar

2.The Mark Multiple Files button on the Results tab->Mark Files toolbar.
