5 System and Configuration Files

Configuration and system files can be implicitly created by application upon calling specific APIs in addition to being created internally by the device. Since these files are essential for proper device operation, it is important that you understand the meaning of each file and when it is required. Failing to preserve enough space for system/configuration files may cause system unexpected behavior.
