Im not sure about this feature as I am quite new to Audacity, but just for confirmation that I am not missing something.
I am moving audio files a lot with small editing/exporting in Audacity, I do not save projects as they are small and never repeated.
When I have Audacity open, I open original audio file (file>open) it opens new window, I edit it, I export it, I close it (save project>No). Now I need to move original, but it is still locked until I close Audacity completely (if the first empty window is still open).
Is it standard behavior or there is way around it?
Were these files requiring FFmpeg - files like WMA, MP4/M4A or AC3?
If that is the problem we did not consciously fix it, though for 2.1.3 we did make improvements in removing memory leaks that would hang on to memory when it was no longer required.
Note that Audacity does not “open” files - it makes a high quality copy of them by default, or for WAV/AIFF it can optionally read the file from where it is. Accordingly the file is not (or should not be) locked, and you could delete the original file as soon as you have imported it. Obviously don’t do that unless you know what you are doing.
To be honest I am not very familiar with multimedia as I am doing different line of work, but files I am usually opening with Audacity are AMR and sometimes MP3.
I did not noticed that behavior using MP3 files (just tried again and it is fine with my 2.1.2), but the AMR files (phone recordings, samr) becomes locked like I mentioned.
