Snapserver 1100

I'm trying to use smartftp 1.0.983 to connect to my snapserver 1100. I can connect and login but I don't see the files on the server. The log tab shows that smartftp is sending a "list -aL". "list" is not a valid command with snapserver. I tried doing a "ls" and "dir" from a smartftp command prompt and they don't work either (I get a "502 Command not implemented" message). These commands (ls and dir) work fine when I ftp to the snapserver from a windows command prompt or UNIX/Linux. Any ideas?

Is there any way to replace the "list" command with "ls"?
