Missing Data File + Missing Blockfiles

I’ve been editing a podcast over the last week. The episode was recorded in Garageband, but exported into a sound file and imported into audacity. The entire episode was divided into multiple parts. Was working on one segment last night, and I noticed that the data file for part 1 ( a file I had finished editing a few days ago) was missing. When I opened the aud. file, it said it couldn’t be found.

Keep in mind I’m a new mac user.

Today when I used Finder to look for the data file, it couldn’t be found. Is there any way to find it again? I remember editing the actual file a few days ago, and there’s no data file in my trash.

Also, for another aud. file, one that I was working on last night, the majority of the work is now gone. Every time I open the aud. file, it says that there are missing blockfiles. I kept saving while I was working, and I’m hoping to recover the part of the sound file that I had already edited.

I’m using Mac OS El Capitan and Audacity 2.1.2. Any help greatly appreciated!!!

You are not editing “an AUP file.” you are editing an Audacity Project. This is an Audacity Project.

_DATA is not a file, it’s a folder holding your sound data. Try Spotlight search, the little magnifying glass in the upper right.

I think it’s still true that default Audacity tries to save your shows to the location or folder that holds the program. That’s an insanely bad idea. From now on, intentionally save work to your desktop and move it from there to where ever you need it. Save has a variable where you can tell the work where to go.

It is a common New User Mistake to record a presentation and then edit it to the final product. You left out a step. Record a presentation and Export a WAV (Microsoft) sound file for safety backup and move it to a safe location. Then go on to editing and post production. If post production goes into the mud, you have the safety backup so you don’t have to record it again.


ACX AudioBook recommends strongly to use an external USB hard drive for audio production. You can get into trouble doing that. There are stiff restrictions on using external USB drives and video people have found it to be unstable.

To dip into Mac for a second, FireWire and Thunderbolt drives don’t have near the restrictions that USB does. If you have a big enough Mac, you may have both connectors.

My little MacBook Air only has ThunderBolt and I bought an adapter so I could talk (and back up) to my FireWire drives.


See Managing Audacity Projects.

You must not do any renaming, moving or deleting of either the AUP file, the _data folder, or any of the files in the _data folder.
