File Transfer Timeout

In the GAS configuration file, the FILE_TRANSFER's TIMEOUT element determines when uploaded files are deleted after application end.

In other words, the timeout value determines how long uploaded files remain available after application end. The files are removed from the temporary directory after the timeout period specified between the TIMEOUT tags elapses. The files are also removed when the GAS is shut down.
<FILE_TRANSFER>
  <TIMEOUT> timeout </TIMEOUT>
</FILE_TRANSFER>
Note:
  1. timeout is specified in seconds.
  2. By default, the value is 600 seconds (10 minutes).
