It’s possible that could cause the problem if the project is on a cloud drive or network drive while the project is open.
Always ensure that the AUP3 project file is on a normal internal drive before opening the project.
Always save projects to a normal internal drive.
It should be safe to move a project to cloud storage after you have closed down Audacity, provided that you move it back to a normal internal drive before opening the project.
For important projects I like to have at least two backup copies on different drives as insurance against hardware failure.
I now have the same problem. Last days all went fine, today I try to open the file and it is empty! I reopened antohter file successfully and worked on it and saved it, and than it was empty when I reopened.
But in the file description it shows content (size 328 KB). What can I do?
have tried to recover a version with Wondershare. It gives me a “aup3-wal” file which I cannot open on my mac. Any Idea? It is too big for an online converter (but it has content, which gives me hope.)
The “.aup3.wal” file is a temporary file used by Audacity while working on a project. When a project is properly closed, any data that is still required by the project is written into the “.aup3” file and the “.aup3.wal” file is automatically deleted. The “aup3.wal” file on its own does not contain any data that can be recovered - it’s a sort of “scratch pad” for Audacity.
this is what it tells me when I now tried to save it:
“value”: “Disk is full.\n\nFor tips on freeing up space, click the help button.”,
