Digital Archive File Upload
For the Error 413.1 - Request Entity Too Large warning when uploading files to the digital archive, the maximum upload size on IIS on the server where the application is running has been set according to the desired size.
For this setting, the application server is logged in, IIS is opened > the application website is selected > Request Filtering > Edit Features Setting is clicked and here "Maximum allowed content length" (bytes)" value is changed.
This setting alone is not sufficient, restrictions regarding file upload in the application code take precedence.
This setting should not be changed without the knowledge of the System Administrator.

If you are working on Linux, you can make these settings on CF (Coldfusion).
After logging into the CF admin panel; CF is restarted by changing the "file upload" preferences under Server Settings > Settings.
Attention: This setting should not be changed without the knowledge of the System Administrator.
