So far, my FTP class was working ok with all the FTP servers I was working with. With one that is causing a problem presently, it always works also ok except in one situation.

This is the known format I have discovered so far:

                            ' This is the standard
                            ' total 4696
                            ' drw-rw-rw-   1 user     group           0 Feb  6 15:46 .
                            ' drw-rw-rw-   1 user     group           0 Feb  6 15:46 ..
                            ' -rw-rw-rw-   1 user     group        4825 May  3  2010 Account.png

                            ' This is also another format we have to support
                            ' -r-xr-xr-x   1 owner    group        78145990 Nov  4  2011 101.zip

                            ' -r-xr-xr-x   1 owner    group            4737 Jan 18 13:50 4A17A7B1.txt

This is a format one server is returning me when there is a file with 0 byte:

-rwxrwxrwx 1 owner group 0 Jan 14 16:25 9A389J11.txt

It seems something is making that FTP server to switch to a corrupted file listing format when there is a file with 0 byte in it. Otherwise, it is returning the file listing as per the first example in the first format.

Can someone explain me if this is normal or if this is controlled by a setting at the FTP server level?
