Temporary File Prefix

Prevents overwriting files by attaching a temporary file prefix, such as FTP_ to the destination file until the transfer completes successfully.

On OS/400 systems, the file name is limited to 10 characters. The temporary prefix can be up to 99 characters long on all other systems.
The temporary file name that is created by applying the prefix must be a valid file name for the operating system of the destination host computer.
