I keep trying to upload an audio file but a message always comes up saying:
Incorrect folder file extension. supports.
I’m using mp3, so it seems like it should work.
What should I do?
Can you screenshot the error you’re getting?
Actually, it’s suddenly working now, so nevermind I guess lol
I had the same issue. When I create a playlist and then bulk import music. However, if i create the playlist, exit out of it andthen add a track seperately, it works without an issue.
Hey there 
I believe that the error message there comes directly from the Foundry client.
There might be an issue with the encoding of one of the files in the bulk import, like a mismatch between the file’s file extension and its content’s actual encoding, though I’m not 100% sure
