Especially, in the cases when thepersistence of the data is a preferred quality.By default, the whole storage is allocated for one file system partition using ‘Flash’ as a logicaldrive name, meaning in practice that the partition is represented as a ‘Flash’ directory off the rootof the file system. You cannot replace the ‘Flash’ name with another although you repartition thevolume. ‘Flash’ remains the directory (folder) name for the first partition. If there is more than onepartition on the storage device, the folder name of the second partition is ‘Flash2’; the third wouldbe ‘Flash3’, and so on.If your application needs the persistent storage, then repartitioning the volume is recommendedbecause a Nordic ID Customizer system uses the first partition to bring update, upgrade, bug fix,and customizing patches to the system through *.pak files stored in the ‘Flash’ folder. In case ofrepartitioning the volume, it is reasonable to reallocate two times the size of the Windows CEsystem image for the first partition, that is, about 30 - 40 megabytes (,or at least 20Mbytes), so thatyour application could use the persistent storage freely within its own partition(s). In the ControlPanel there is an applet called ‘Storage Manager’ with which you can repartition the persistentstorage. Note that you can create only FAT file system partitions on the storage.The storage in a nutshellStorage technology NAND FlashStorage capacity 128 Megabytes Note that the ‘Storage Manager’ (don’t confusethis with the Control Panel applet being the sameby name) allocates half a megabyte for managingthe device.
