Nearly every single Microsoft Access “database” I use has a proper database attached instead of using the internal Jet Engine, this means data is not actually stored in the Access “database” and I therefore call them Access Frontends.
Compiling your Access front ends to ACCDE provides a compiled copy of your Access Front End.
I find it is much harder for users to corrupt the Access front ends when compiled.
Making a compiled Access ACCDE file a runtime file is as simple as renaming the extension from ACCDE to ACCDR, all this does is make sure full installs of Microsoft Access launch in the runtime mode. It also means you can use the Access Runtime which is free from Microsoft (However always ensure you read through the EULA).
As runtime mode is used, its easier for development as I don’t have to hide menus.

To create an ACCDE from a Microsoft Access file, open the file in question, ensure your “Visual Basic for Applications” Code compiles otherwise the next step will fail.
Go to File –> Save & Publish –> Make ACCDE
Save the file in the location you want.
You can now rename the extension from ACCDE to ACCDR.
Now test the file launches.
