How do I open a project accidently saved as raw data

What a plonker! I accidently saved the project in 1511 tiny pieces of raw data!!! Can anyone tell me how I can import them all together as they were when I tried to save the project PLEASE!!! …I think they are raw data? they are .au files …I hadn’t finished the project and was saving to continue the next day… so it had about 4 or 5 different stereo channels
Thank you

see this page in the Audacity Manual:


Audacity should have made an audacity project file. Like project.aup. That combined with the raw data is opened by Audacity.

There are youtube videos that explain this.

This is a project.

You need both parts to put your show back together. Double click on the .AUP file.
