reading parts of a large data file

Good morning!

Somewhere I read that a statement such as

  let fullFile = Storage.read('DataSet');

would just copy a reference to the data in flash - and not transfer the whole file.

However, when doing so on my device, I get a LOW_MEMORY error. Am I wrong with my assumption?

If so, it would be nice to get an extended read operation with the following signature

  Storage.read(file-name, offset, length)

in order to read just parts of a file (similar to Storage.write)

Using StorageFile instead is not an option as such files do not support binary data (because 0xFF is used internally)
