The folders do work fine now, but the smartass-heuristic does still fail for lnk files.
- Create a file called C:\mbr.old.lnk
- understand, that ros by default does never show the lnk extension in explorer filebrowser, so it will show this file with the link-icon-overlay, but will only display its name as C:\mbr.old
- now press F2 on that file
"mbr.old" should be preselected for the editing
