AllSync & AllDup

Greetings. New user here.

As someone suggested on this forum, start simply, so I selected a folder containing 4 files and scanned that path with AllDup.
One folder containing 4 files appeared in search results. I ticked all of them and pressed delete - all files appeared to be gone.

But when I re-searched the previous path the 'deleted' folder/files appeared again in search results.

I'm doing something wrong, just not sure what.

Thanks and appreciation for any help.

The DEL key removes all highlighted groups and/or files from the search result.
Use the shortcut manager to define another action for this key.

Sorry but I could not locate 'shortcut manager' in Help. Is that what it's called or something else?

Thanks

See search result -> menu bar - > options -> Hot Keys
