A user who deletes a directory tree by accident will have to salvage all data in subdirectories one by one. This can be time consuming and highly inconvenient. Enabling the OES client to work in a recursive way on directory trees will facilitate this task. The same applies for salvage with CIFS (NFARM on Windows and the future version for macOS). An option to select a time mark for all subdirectories will be needed in order to make this work ("salvage all files I deleted today in this directoriy and all subfolders").
