.aup loads without errors but only one track is loaded


I am using Windows 10 and Audacity 3.0.4. I was using an older version of Audacity previously but I’m not sure what version. I had to reformat my computer and reinstall Windows. Most of my projects load fine but a few projects, when I load the .aup file it only loads a single track. I can verify the project folder contains all the tracks but they do not load with the project. This only seems to be the case with a few projects. Thank you in advance for any help or guidance!

Please attach one of the AUP files that you are having problems with.
(See: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1)

here is one of the attached files that isn’t loading the full tracks
only you.aup (12 KB)

How many tracks are you expecting? The AUP file shows one stereo track.

It should have at least six. They are in the project folder but just don’t load with the .aup file. I’m wondering if maybe that file was corrupted in some way when I backed it up before reformatting

Are you assuming that each sub-folder in “only you_data” is a track? If so, then that’s an incorrect assumption. The directory structure in the “_data” folder has no relationship with the project tracks - the audio data for any audio track may be in any of the folders.

Audacity keeps track of where all the audio data goes using the AUP file.

This screenshot shows the “” sections (collapsed so that it will fit on this forum page).

channel="0" linked="1"

means that this is the left channel of a stereo pair.

channel="1" linked="0"

is the right channel of the stereo pair.

The AUP file appears to be complete and without any errors.

no, not at all. I can load the data files from the subfolder into Audacity and they contain all the tracks that are missing, they just aren’t placed in the recording where they should be, and there are deleted tracks and scratch tracks in there.

If Audacity closes normally, it deletes any AU files that are not listed in the AUP file.
