There is a new operation available in the System Functions menu in the System Wide Checks page. ( The page needs to be reset once when the FEEs are powered before this function will appear )

Check the Options files are all the same size

Using this function will provide a list of the file sizes of the Options/< fee name >/CONTENTS files along with the last time they were accessed as a list.

It's up to the user, at present, to interpret the results but more is possible if required ....
