A device management technique used to artificially compartmentalize various types or values of data on a storage medium. On a mobile device, the device manufacturer and/or the service provider may use storage segmentation to isolate the device’s OS and preinstalled apps from user-installed apps and user data. Some mobile device-management systems further impose storage segmentation in order to separate company data and apps from user data and apps.
