accesing filestream denied for SharpZipLib for Unity3d iOS

i am trying to unpack a .zip file but when i try to copy the zip stream to the file i get:

UnauthorizedAccessException: Access to the path "/var/mobile/Applications/7209CA86-E88D-4BAC-B285-2912B982E8C0/Documents/Inbox/Book.txt" is denied.
  at System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) [0x00000] in <filename unknown>:0 
  at System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize) [0x00000] in <filename unknown>:0 
  at System.IO.File.Create (System.String path, Int32 bufferSize) [0x00000] in <filename unknown>:0 
  at System.IO.File.Create (System.String path) [0x00000] in <filename unknown>:0

Book.txt is a file of the .zip file.

Here is the code where the problem appears:

using (FileStream streamWriter = File.Create(fullZipToPath)) {
					StreamUtils.Copy(zipStream, streamWriter, buffer);
				}

The code works well on OS X but on iOS i can’t get it fixed. What is the problem?

What’s the “fullZipToPath” path? You have to use Application.persistentDataPath in order to have access to that file.
On mobile devices, paths to files are restricted by the OS, which is not that restricted on the standalone platforms.
