I don t like   paths objectAtIndex 0   because if Apple adds a new folder starting with  A    B  oder  C   the  Documents -folder isn t the first folder in the directory   Better   NSString  dataPath    NSHomeDirectory   stringByAppendingPathComponent   Documents MyFolder    if     NSFileManager defaultManager  fileExistsAtPath dataPath         NSFileManager defaultManager  createDirectoryAtPath dataPath withIntermediateDirectories NO attributes nil error  amp error     Create folder

I don t have enough reputation to comment on Manni s answer  but  paths objectAtIndex 0  is the standard way of getting the application s Documents Directory  http   developer apple com library ios documentation iPhone Conceptual iPhoneOSProgrammingGuide StandardBehaviors StandardBehaviors html   apple ref doc uid TP40007072-CH4-SW6     Because the   NSSearchPathForDirectoriesInDomains   function was designed originally for   Mac OS X  where there could be more   than one of each of these directories    it returns an array of paths rather   than a single path  In iOS  the   resulting array should contain the   single path to the directory  Listing   3-1 shows a typical use of this   function       Listing 3-1  Getting the path to the   application   s Documents directory   NSArray  paths   NSSearchPathForDirectoriesInDomains NSDocumentDirectory  NSUserDomainMask  YES   NSString  documentsDirectory    paths objectAtIndex 0
