Why did the file type change from cba to cbdb?

[Craig A. Guerin]

Can you keep using the old format in v2017?

Was it because the code was updated?

[Steven L. Dasinger]

If you are using CB 2017, it would use CBA as the file extension.

When CB was rewritten to CB 2020, the file extension was changed to CBDB.

If you are using CB 2020 or later, if you try to open an older CBA file, it will read it (it won't change it) and create a new CBDB file.
