So, if we want to see a new version of a file rather than the original, we just need to put the new version in the proper folder location and regenerate. The regenerate process will automatically hide any archived file that has a corresponding file saved in the folder structure or make it visible if the corresponding file in the folder structure is not present. The files present in a big archive can be visible or hidden and this is achieved modifying the corresponding BH file.
In this way it is much more easy to recover the original functionality of the game if something in the editing goes wrong.
File Master 14 has a few differences when compared with previous versions: the most important is that it does not allow you to modify the original.
