"Support for the LIST command will be removed. In its place MLSD will be used as defined in RFC 3659. The problem with LIST is that its output isn't specified. As such it is impossible to reliably obtain directory listings using LIST. MLSD on the other hand uses a well-defined listing format. MLSD has been introduced more than 8 years ago, by now all server administrators had have more than enough time to upgrade their servers to be MLSD capable." -- https://forum.filezilla-project.org/viewtopic.php?t=36597
