In my application I have to read a file that have be created by another application on my device.
How it can be done. The file must be located on file System's root directory
Thanks,
Eyal.

Unless you are writing for Jailbroken devices, you can't access files outside of your app's sandbox.
So, for apps distributed through the App Store, you can't do this.

Could you please point me to the documentation, where the meaning and format of all files inside iOS app source is explained? I'm trying to understand the architecture of iOS applications, behind the UI of Xcode.
Change the extension on the app from ".ipa" to ".zip". Then double-clock to unzip. Examine the unzipped folder's contents.

I have created an iPad app which downloads some confidential data and stores it in the document folder.
I was reading about the security of data on an iPad, and I found that there are some applications which reveal all the data and folders of an app.
Is there any way to avoid that, and to secure my data or a whole folder?
For storing confidential information use KeyChainItemWrapper

I would like to distribute some music files with my application.
What is the way to add a media from the application folder to the media library?
Unfortunately no way to write to Music Library.
However you can add the files to Bundle and play from there and copy to Document directory. You can't change anything in the Music Library, only read permission is granted for third-party libraries.

I am downloading an MP4 from a server by writing the file data directly to the app's documents folder. My question is - is there a way to start playing this file before it is fully downloaded?
According to https://trac.mplayerhq.hu/ticket/748 this is not possible because important information is missing from the file. I haven't studied the container format myself to confirm that.
