WebMin File Manager to Set SuExec compatible permissions 755/644

Is there a sequence of operations that can be performed in File Manager, using the Info box, to set permissions recursively to the 755/644 that SuExec demands?

It seems that when I select the recursive option, and either “all directories” or “all files”, that something is going wrong…maybe that directories are being considered files, or something like that?

Thanks,
Ken
