Zip files are extracted automatically - are they?


just used the WiFi-Server to upload a Zip file that contains 39 wav-tracks (exported from Cubase 7).
The help says, that zip-files are extracted automatically. However I can’t find them. I uploaded the file to audio/user.
Is there a way to import audiotracks directly to the audio-folder within the project? I can upload them via WiFi-connect but they don’t show up anywhere.
