Net::FTP::Recursive won't descend into to subdirectory unless the name of the subdirectory matches your pattern. For example, if there is a directory
Net::FTP::Recursive will descend into "PowerEdge R810" since it matches. However the subdirectory "TextFiles" does not match your pattern, so Net::FTP::Recursive will ignore it. Net::FTP::Recursive dos not consider a child directory to match simply because a parent did.
What I was suggesting, was that if you happen to know the where the various "PowerEdge" directories are, you could search each of them separately, omitting the MatchDirs option, thus circumventing the limitations of MatchDirs
