Trying to attach a 7g file . What is the limitation AgilePLM 9.3.3
Check your “Upload File Size Limit (in MB)” settings (Admin -> System Settings -> Viewers and Files). If it’s set to zero, you have no limit and Agile will let you upload your 7GB file. As long as the back end server itself isn’t full, you should be fine.
If you are using iis proxy:
Select Default Web Site in the Connections pane, open the Request Filtering in the IIS section.
Click Edit Feature Settings in the Actions pane and adjust the Maximum allowed content length (Bytes) and Maximum query string (Bytes).
