the data file was not save

Hi, When I saved my project only the .aup and the small .au files were saved. The _data file was not saved for some reason! Is there a way to play/recover this recording using the .aup and the .au files??

To cover bases, please read the pink panel at the top of the page and tell us your version of Audacity and version of Windows.

Have a look at for how projects are structured. There is an AUP file and a _data folder (not data file). The _data folder contains the small AU files.

To reopen the project in one piece in Audacity, open the AUP file.

Only Audacity can open AUP files. Use File > Export… to save your work as an audio file that other applications on your computer can play. Have a look at this page about the Export Audio dialogue:


Thanks for the reply. The .aup is not playing. When I click it, it says “Couldn’t find the project data folder etc” although I do have a folder with the small .au files for that recording. I wish I can give a screenshot of what’s saved just to be more clear…

You still have not told us your versions of Audacity and Windows.

The current version of Audacity is 2.0.6 from That is the best version to use.

Have you been renaming or moving the AUP file or _data folder? You can’t do that.

I suggest you attach the AUP file here. Please see here for how to attach files:
