PUT Stream (Multiplart):With this option a header is created which goes with a trick into the body and writes the necessary information of the file into the body. Important! The only way to write something at the end of the body is to write this information into the file.
After the upload is finished or canceled the plugin removes this information from the file.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
PUT Stream (Copy Multiplart):This option also writes information to the file. But a copy of the file is created before and the info is written into the copy. The copy will be deleted after the upload. Making a copy of a large file can lead to freezing because it is done in the game thread.
