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! Dan
