0x0615 Append or Replace

Use this TLV in the Record File Start message (0x011E) to specify whether to append to a file or to completely replace the file.

You can set the "File Not Found" behavior so that if you attempt to append to a file that is not found, you can create a new file or fail the open command.

The Append or Replace TLV is ignored for temporary records, which are always replaced. It is also ignored when copying a temporary record to a file.
