iOS storing files rules - Storing audio files on iOS app

Question

I need to be sure I am doing the right thing:

In my app the user can download audio files from the server. I don't want those big file to be backed up as he can re download them when ever he needs to.

My app is addressed for iOS 4.0 and above.

So as I understand I need to store the files is the documents directory and set a flag for the directory to not back up ?

Am I correct ?

Instead of putting them into the "Documents" directory (which gets backed up to the cloud), why not put your audio files into a "Cache" directory (specifically "/Library/Cache", which does not get backed up)?

Here's another question here on Stackoverflow that may help give a further answer to your question.

Won't those files be deleted when I empty the cache of the app ? – shannoga Jul 07 '12 at 19:40
Yes... if you don't want to use "Cache", then set the "Do not backup" flag on whichever directory you decide to use (as specified in [this answer](http://stackoverflow.com/a/8145650/981049)). The big issue here though is that this flag is 5.1 & newer only – Michael Dautermann Jul 07 '12 at 20:51
What about the temp directory? – shannoga Jul 08 '12 at 09:08

You can also prevent files to backed up: https://developer.apple.com/library/ios/qa/qa1719/_index.html
