Interesting... I'll have to look into this one. :)

Bill, I recently found an Access Add-In vcs

Not sure how you backup at the moment, maybe OneDrive.

With this new tool it exports all the Tables, Forms, Reports etc and you can see the code used in these.
It may look a little weird at first but it is readable in Notepad.

It's to use with a Version Control System like git which you could upload to GitHub.
This way you can easily compare different versions.

Hopefully the README in the project explains it in enough detail but I do want to make a video on it.

Thanks Alex.
Question: How can I change the repository that vcs uses to store the output? Currently it seems to use the directory that the access database is in, but I'd like to specify a central repository. Thanks again for the help..... Bill D.

I'd have to double check if there is a setting, there are quite a few.

Another option is a bat/vbs/ps script you could run afterwards which moves the output somewhere else, it's an extra step but should do the job.
