thanks for your help.
its because version 6 portable is not released yet, and the beta has some issues.
that's why I want to use the version 5 portable.
I have version 6 on one PC and version 5 portable on another PC.
I want to export the data (or create a backup) from Version 6 and import it into version 5.
But there is no format that makes this possible.
Version 5 only accepts .wallet or .db files
Version 6 does not export or backup in those formats.
What can I do?
