Internal Storage
Internal storage is the memory where most applications and data are stored.
The operating system protects all data and applications from power-related loss. Because the operating
system mounts the entire file system in persistent storage, ET1 devices provide a reliable storage platform
even in the absence of battery power. Internal Storage provides application developers with a reliable storage
system available through the standard ext4 file system. Data in Internal storage is lost upon a Factory or
Enterprise reset.
Internal Storage is approximately 2.3 GB (formatted). To view the available internal storage, touch Settings >
Storage.

Enterprise Folder
The Enterprise folder (within internal storage) is a super-persistent storage that is persistent after a reset and
an Enterprise Reset. The Enterprise folder is erased during a Factory Reset. The Enterprise folder is used for
deployment and device-unique data. The Enterprise folder is approximately 128 MB (formatted). Applications
can persist data after an Enterprise Reset by saving data to the enterprise/user folder.
