Creates a list of path strings for the specified directories in the specified domains. The list is in the order in which you should search the directories. If expandTilde is YES, tildes are expanded as described in stringByExpandingTildeInPath.
You should consider using the NSFileManager methods URLsForDirectory:inDomains: and URLForDirectory:inDomain:appropriateForURL:create:error:. which return URLs, which are the preferred format.

The directory returned by this method may not exist. This method simply gives you the appropriate location for the requested directory. Depending on the application’s needs, it may be up to the developer to create the appropriate directory and any in between.
