The NSFileManager class enables you to perform many generic file-system operations and insulates an application from the underlying file system. Most file operations can be performed using the shared file manager object. In iOS and Mac OS X v10.5 and later, you can also create a unique instance of NSFileManager in cases where you want to use a delegate object in conjunction with the file manager.
In Cocoa applications, a file manager object is usually your first interaction with the file system. You use this object to locate, create, copy, and move files and directories. You also use this object to get information about files and directories, such as its size, modification date, and BSD permissions. You can also use a file manager object to change the values of many file and directory attributes.
Thank you, I am very new to this. Where do I actually put this code? Any examples?Look into what iOS's implementation of NSFileManager lets you do :
