Hi thanks for the question.

Memory defragmentation is technically optional in the MULTOS specifications.

However I know for sure that Multos International implementations do memory defragmentation as part of application deletion and think that Samsung implementations do the same. I’m not sure about the other implementers but could find out. Who is the implementer of the chips you are using?

You can find out by sending the GET MULTOS DATA APDU – the implementer ID is the 4th byte. The latest MUtil can send this command for you and interpret the result.
