When I open a version 4.0.1 file with Edge 5.0 it automatically upgrades the file but it duplicates the project folder and appends the suffix "_upgraded" to it.
I need the folders to remain named exactly as they are without having to go back and change them.
Is this a setting I can fix somewhere or a bug in the new version?
The upgraded version will always create a new folder suffixed with "_upgraded" when you open older composition, to preserve the old composition, because there has been significant changes in the runtime used and files generated by new version.
The composition saved in updated Edge is not backward compatible with older verison of Edge, as whole of runtime has been shaked-up to make it leaner and more performant.
