I'm not sure I understand - could you give an example?
If you call
StorageFile.write10000 times, writing one byte each time, it'll use just 3 files worth of data. The file number does not increment based on how many writes you're doing, it's based on how many 4k pages you're using.The restriction on using 0xFF in
StorageFilefiles is specifically so they can have that behaviour.
