Does flashfxp handle MLSD data of the form type=OS.unix=slink:/path/to/target ? I think servers can return symbolic link data using that form, and a number do, but it isn't exactly standardized. I found a link at
http://www.rfc-editor.org/errata_search.php?rfc=3659 if you search for "symbolic" which shows an RFC approved method to return links using the unique identifier fact with an entry for the link and the target, but I think servers cheat and just return the non-standard link format without the additional result.
