Universal Data Back-Up

Universal Data Back-Up
Version: 3.0

Introduction

Ever go to open your RPG Maker XP/VX project, just to find *gasp* an Unexpected File Format error!? This system does regular back-ups of all the files in the specified Data folder, and re-writes them to a backup directory. Not only that, but this script is universal meaning it'll, in theory, work in any standard Ruby library just as well as it does with RGSS/RGSS2.


Features
Saves all data in specified data directory.
Writes all data to specified backup directory.
Doesn't just read default RM Maker files.
Writes file as it origionally was, with same data extension.

Script

Code:
