Total Commander

I use FTP sometimes for transferring large files via my server.

After download I have to manually delete the transferred files, would be nice to have a MOVE possibility or a way to add Delete commands to the download list.

Moving files from/to an FTP server is not supported, for security reasons. If you move a file in wrong mode (e.g. text as binary or vice versa), then the target file will be unusable, and the source file will be gone! Also some ftp servers report "Transfer OK" even for aborted transfers.
