Surely I'm not the only one who's done this. Using the Browser, I thought I was grabbing an audio clip to drag into a project. I was going for a .wav file from a different Sonar project - But what I did by accident was highlight the name, and when I clicked again, naturally the name disappeared, and I was left with a file just called ".wav"- The clip played fine in the project, but obviously I had to fix what happened, since the audio clip was originally associated with a different project.
Not being positive what the original name was, I opened that project, and when the missing audio dialogue came up, I copied the name of the "missing" file - then went to that project's audio folder and pasted in the proper name for that file again.
Yikes!- I was just moving too fast when I grabbed and accidentally erased the file name, but maybe this mistake is too easily made? Why even have the ability to re-name things in the browser? - But that's probably just standard Windows behavior that could be impossible to over-ride.
I think the only advice on this is - be careful grabbing your clips!
