I have audacity 2.1.2 and windows 7. I have a particular project file that I am unable to open; it has an error that reads “… is an audacity project file. use the 'file>open command to open audacity projects.” Well, that is how I tried to open it.
I can open other projects, just not this one.
I know that the file is saved because I have closed and opened it before.
This happened shortly after updating to Audacity 2.1.2, but all of my other files from the older version still work.
Both the project file and the data folder are in the same folder.
That show may be lost. If you damage an original recording, sometimes we can reconstruct the show from the fragments inside the /DATA folder (it’s not a file). But if you lose an AUP file in the middle of editing, then the /DATA folder is scrambled.
