Rev 1.1 11/29/2004 11:26:00 PM JPMugaas
|
|
This should now support SuperTCP 7.1 running under Windows 2000. That does
|
|
support long filenames by the dir entry ending with one space followed by the
|
|
long-file name.
|
|
ShortFileName was added to the listitem class for completeness.
|
|
|
|
Rev 1.0 11/29/2004 2:44:16 AM JPMugaas
|
|
New FTP list parsers for some legacy FTP servers.
