You have to keep the History (of whatever you want to show). If this is something like file manager, if could be just navigation history. Actually, managers like that can have several histories, such as history of commands, locations (navigation), etc. The history is a list of some objects (mostly strings, in case of locations or commands) with the current index in list, or reference to a current element, for a linked list. The list should grow to certain length and then too old data should be removed. Therefore, the adequate data structure could be a doubly linked list. (If you only needed "Back", it would be much simpler: the Stack of strings.)

On buttons, you get next/previous data element, move current in a correspondent way, navigate there (issue command, etc), and refresh enabled/disabled status of the buttons (because, depending in available data and location, "Back", "Forward" or both actions should be disabled.

Design it all and add to you code.
