The file size of files uploaded to WebCenter is limited to the setting defined in IIS on the Web Server. When trying to upload files that exceed the configured file size limit, an error is displayed in WebCenter.
This article describes how you can modify the file size limit in IIS.
IIS 7 has a limitation on how much you can upload at once (30 MB). To extend the upload limitation from 30 MB to 2GB, follow these steps:
Connect to the Web Server and open Internet Information Services (IIS) Manager.
Select the website (for WebCenter this is mostly the "Default Web Site") for which you want to enable large file uploads.
In the main window, double-click Request Filtering.
Once the window is opened you may see a list of tabs (file name extensions, rules, hidden segments etc.). Regardless of the tab you select, right-click in the main window and select Edit Feature Settings.
Modify the Maximum allowed content length (bytes). Change the value to 2147483548 to be able to upload files to 2 GB.
Open a Command Prompt as administrator and type the following: "iisreset". Press Enter.
