Hi,
1. When a large number of duplicate files are listed , and selection assistant is used (or otherwise) and the duplicates are marked. There may be certain groups totally ignored , and a marked duplicate group lying deep below (when the files are huge). After the marking is completed , a filter to show only those groups which have a mark , omitting the rest.
2.Inverse of "Preserve files in the path". Might be a few files (duplicates) are new and loaded into a particular folder. I wanted those files only in the PARTIULAR folder to be deleted. Now I have to index by path and select.Perhaps a lazy way out . But who knows this feature may be used by some.
