Set it to xmaAutomatic to let the library move the temp file. This is the default behavior and should be used unless you're experiencing problems in particular situations like target destinations on a unreliable network connection.

Set it to xmaManual to let the event handler move the temp file. Using this value means that the library will not move the temp file itself. The library will not check for success or failure of the file operation. The event handler may implement any algorithm to move the temp file to its final destination. The event handler must also delete the temp file. When the event handler returns control to the library, the library assumes moving the temp file is completed.

Set it to xmaAbort to abort the operation. The library will assume the move operation failed and return a xerMoveTempFile error code. The library will not perform any action on the temp file.
