The Content Locker solution gives enterprises a high level of control over how data is accessed and downloaded on the mobile devices. Policies can be set to control access (enable / disable offline viewing), transfer method (cellular or WIFi only), download type (on-demand download, or content pushed by download date, with options for mandatory documents), and download priority (high, normal, or low).
When using the app for the first time you'll be prompted for a Group ID, username and password or authentication token (generally provided by your company's IT department). Once logged-in you are able to browse and view content as specified by IT administrators. The app also supports the downloading of content from both AirWatch and SharePoint data stores, allowing it to be viewed even if your device is offline. There's also support for Personal Content (users own data), with the standard file/folder and upload/download operations.
