Content overview
Last updated May 30th, 2025
Upload various types of content, such as documents, images and videos, on the Knox Manage cloud server and distribute them to device users directly. Content can be uploaded without a storage limit and sent safely and quickly through the Content Delivery Network (CDN).
For devices running Android 10, if a content file is changed or the file name is modified, existing on-device copies of the file are not automatically updated. You must manually re-deploy the file for the changes to be reflected.
Conditions for uploading content files
The following conditions must be met to upload and distribute content:
- Only enrolled Android devices are supported.
- For devices with a screen size smaller than 8 inches, device users can only view content in portrait mode.
- Content files must be 4 GB or less.
- Only certain file extension types are supported (see following section).

Auto-deletion of content from devices
After a device has downloaded assigned content, the content will be automatically deleted from the device under the following circumstances:
- The user account is assigned to a different organization or group.
- The device is assigned to a different group.
- The device is unassigned.
Once the old content is removed, the newly-assigned content gets automatically downloaded.
