Thank you.

Hi there,

Thank you for the wbmeeting.

And I have another one question:

- What is *.nlb file type?

It used to work under 8.* version but doesn't under the 10.* version.

Can I convert it somehow, or maybe you have another idea for that.

Thank you.

Hello Oleksandr,

nlb files (comes from Nevron Library Binary) are binary files that are use for the binary serialization.
However, this files are not backward compatible. Only nlx files are backward compatible.
