Can Different Versions of Scrivener Access the Same Project File?

This is great news. I did receive a message that the file I was attempting to open was created with a new version of the software. My guess is that I will either need to go to a version 2 backup or export from version 3 into version 2 format. I will attempt that later this evening. From your reply I gather you may also be going through this process and I noticed you use the Windows version as well. I too have the Windows version, but have not yet attempted to open the version 3 files from that platform. Do you have any experience in that process as well?

Thank you in advance for your response an please accept my apologies if my questions seem basic, but I have limited experience with Scrivener (but love the app).
