Integrity check of a .dat file stored on eMMC

Hi,

In my S7 application I am dealing with a file *.dat that is stored in the eMMC (I'm using FileX). At the startup, before reading the content of that file, I need to perform a sort of data integrity check, to ensure the file or its content is not corrupted. Is there a (possibly simple and fast) method that I could use to achieve the goal? Perhaps is there something "built-in" in the FileX framework?

Thank you,

regards.
