I tried to import about 1200 sounds by copying over to a subdirectory of the Assets directory of my project, but got an error about Temp files when getting about 70% the way through.
“Opening file Temp/importedAudioTempPrimary:”
If I “try again,” it continues to fail.
If I then press cancel, it complains about not being able to open a file that actually exists on the hard drive even after the crash.

I had the same problem a few times with a lot of sounds as well. The Universal Sound FX is probably a good package to use for testing this issue as it has 1000’s of sound files.
Update: If I delete some of the files, it works fine.
I have plenty of space and memory available.
Thanks for the input too, Nathan. 
We’ll investigate, thanks.
Confirmed, fixed for an upcoming build.
As a workaround, you should be able to import audio files in smaller groups.
Thanks Tak!!! you guys rock!
Thanks Tak, I can’t wait for the next build
No problem Jacob, thanks for reporting it in the first place, because once I had my project imported I forgot the issue even existed.
Hi Tak,
Things look better in 5.2.2f for the importing, but I still have trouble. Somehow the files aren’t getting closed or something. I am importing about 500162 files.
Here’s the exception.

Hope that helps!
Best,

Levi, I can confirm this as well that the bug is still there. After running Unity a few times it finally goes through. From the error message, it seams to get hung up with the Temp directory.
“Opening file Temp/importedAudioTempPrimary:”
This is while importing the same sound pack that I mentioned above. I’m on Linux Mint 14.2 and it happened earlier on Ubuntu Mate 15.04
Hm, jacobgmartin’s error looks like it could actually be something different - if you’ve got the repro project for that, I’d like to use it for testing.
NathanWarden - that’s odd, I used that package for finding the issue and testing the fix. I’d better doublecheck and make sure the fix actually landed in the release branch.
I also got the audio temp errors sometimes but the stacktrace i posted did happen once also. It is probably related I guess.
I am guessing the fix didnt make it into the release because it isnt fixed at all and also because the fix was confirmed on 10/20 and the new buid has a 10/18 date. I dont know if these dates mean anything but i was hoping it was something simple like that and a repackaging would include your new fix. .
Thanks Levi, much appreciated. Almost everything else is running great.
