Large File Uploads

Application Settings

When uploading multiple documents using the Multiple File Upload tool, you may see this:

To adjust this setting:

  1. Hover over the admin icon in the toolbar > click App Admin
  2. Click Manage Fields from the right menu
  3. Hover over the File Upload field > click the pencil icon
  4. Adjust the max file upload size: mceclip0.png
  5. Click 'Save' to complete this change.

Server-Side Changes

Windows Server and IIS come preconfigured with file upload limitations you may run into while uploading files to the intranet.  To adjust these settings, complete the following on the Web Server.

Note: Larger files can use up the available hard drive space so we recommend limiting the file sizes allowed to some degree, or using external hosting services for large video files.

Errors commonly encountered are:

  • Page cannot be displayed
  • 404 File not found
  • Check IIS settings for the maxRequestLength and maxAllowedContentLength

MaxAllowedContentLength: 30 MB limit - IIS 7+

This is used with Multiple File Upload and uploading videos. The size listed is in bytes. If you're looking to upload a 300mb file, then this would be 314572800 bytes.

The above example indicates where within IIS these settings will need to be adjusted. Please note that changing the setting at the Intranet folder level is only required if your intranet requires /intranet in your URL (e.g. https://myintranet/intranet/).
You may need to use a converter (http://www.unitconversion.org/data-storage/megabytes-to-bytes-conversion.html) to determine the correct setting.

maxRequestLength limit

Unlike the MaxAllowedContentLength, this is set in Kilobytes. Using the 300 mb example, this would be 307200 kb

Adjust maxRequestLength limit (used with Multiple File Upload and Message Box widgets/fields) as follows:

  1. Navigate in IIS to the Configuration Editor for the intranet site, if the site URL contains /intranet you'll have to select the intranet folder within the site
  2. Open System.Web > httpRuntime as shown on the image below
  3. Look for maxRequestLength and executionTimeout and adjust as necessary (default is typically 4MB)

Note: the maxRequestLength cannot exceed 2097151 KB.

  1. Tap the enter key after updating each value
  2. Click apply on the right side of your IIS screen

 The web server will need enough time to process the request, the example image below uses 10 minutes instead of the default of 1 minute and 50 seconds.

To determine the minimum bytes that you'll need to put into this setting, use the following converter http://www.unitconversion.org/data-storage/kilobytes-to-megabytes-conversion.html (e.g. if you need 100MB, the value would be: 102400 as shown in the image below)

The above example indicates where within IIS these settings will need to be adjusted. Please note that changing the setting at the Intranet folder level is only required if your intranet requires /intranet in your URL (e.g. https://myintranet/intranet/).

Connection Reset

If you're getting a connection reset error message, you'll also have to increase the Connection Limits timeout in IIS. With the Intranet Web Site selected, click limits in the right menu, and increase connection time-out from 120 seconds.

Connection was reset - Network Configuration

On some networks, there may be an option within the firewall software to set an upload file size limit.  If this is set, the user may get some variant of the "Connection Reset" error. Either remove this setting or set it at a higher value.
