Class FileManager

java.lang.Object
  org.alliance.core.Manager
      org.alliance.core.file.FileManager

public class FileManager
extends Manager

Keeps track of all files used in Alliance. Contains the ShareManager, DownloadStorage and AutomaticUpgrade. Should contain FileDatabase but it's actually contained in the ShareManager. Also contains the CacheStorage (that's hardly used right now).

This is the place to check if we have a certain root hash (complete or incomplete), to get FileDescriptors and to do file searches.
