I'm using Camtasia 9. I'm editing 5 TREC files in my Media Bin which I will ultimately concatenate together in the finished presentation. I edited each of the first 3 files using Noise Reduction and also Audio points to remove breathing noises. I used File>Save repeatedly and constantly throughout the process. After editing each file I Removed it from the Track and dragged down the next file from the Media Bin to do the edits. Now when I drag any of those 3 file that I edited down into the Track an play them I see that none of my edits are there. Each of the TREC files are in their original folder with their original dates. The TSCPROJ file is in the Camtasia Projects folder with today's date and it is 36 KB. How can I reload my edited TREC files in the track to see the edited version and make further edits if I like? What am I misunderstanding or missing?
