Section 4-5

Any existing file with the same name in the remote host (Memory Card or EM

File Memory) will be overwritten by the contents of the transferred file.

If an error occurs during file transfer, the file being transferred will be deleted and the transmission of that file will end in an error. However, mput execution will continue and remaining files will be transferred.
