1.Create an empty project
2.Copy an audio file A.wav to your desktop
3.Drag and drop the audio file A.wav to your project
4.Modify the audio file A.wav in your desktop (for instance mute a part of it) and save it with the same name.
5.Drag and drop the audio file A.wav to your project
The result of step 5 is that the old file A.wav is copied again to your project without the modifications of step 4.
Cubase should detect in step 5 that A.wav was modified since the last time and import the new version of it when you drag and drop it again.
This happens in Cubase 10.0.60, Windows 10, 64 bit
Can somebody confirm if this happens in Cubase 10.5.20?
