Parent folder context menu selection doesn't work

[00]

Trying to reproduce Mark By Location functionality in DC4 where I was able to delete all duplicates found in a parent folder and all its subfolders. I right-click the duplicate file and select 'Parent Folders' (specify the folder) -> 'Mark' -> any and all options fail to mark anything.

Bump.

Any help with this? Is DC5 still in alpha/beta?

Thanks

It should work as far as I know - are any files protected? Any ususual drive/path names?
