Its really a performance concern. We need to do this fairly regularly on a
large repository (over a WAN I might add) and asking the server for all
files and directories when we really only need a directory listing is
really a huge time sink (a 100:1 file to directory ratio would result in a
listing time of 100 times slower). Grep and the like only format the
output on the client side (which is easily parsable - we do use xml to
parse) and don't relieve the performance burden.
Thanks!
