Use companion files and not allow loading/saving other workbooks

Hello!
Is it possible to use companion files and not allow loading/saving other workbooks (even with VBA code) at the same time?
Thank you very much!

It is possible to use companion files and at the same time "Do not allow loading/saving other workbooks (even with VBA code), provided you inform XLS Padlock that you want to open a file other than the main one. To do so, you must use VBA code available here :

Hope this will be a solution to your problem.
