how can used SDcard to control led offline

Hi all,the first i say sorry because my english not good ^_^, I want to control leds offline via SDcard and i read a website in china, they used this module SD card controler: http://www.ledwalker.com/product_details.aspx?pid=3&sid=15&id=204 and used software Ledwalker to make some project and set addresses, we can design patterns by Ledwalker software and store files in SD card of controller. They can control LPD6803, D705, D709, WS2801, WS2803, DM621, UC6909, TSL3001, CYT3005, TM1803, TM1804.. It so cool. I like it so much but I can't buy this product, I want to used Ledwalker (or other same software) to set adresses and make some projects with effects, afterthat i copy to SDcard from Arduino shield (Ex Arduino Ethernet Shield)and control offline. How can i do that to control leds offline via SDcard. It very kind if someone give me a little example to do that

Please help me, I mean that I used ledwalker to make a project, file .led ; and copy this file to sdcard in board Arduino , how can i make my arduino can play that file and control led same module sd card controller : http://www.ledwalker.com/product_details.aspx?pid=3&sid=15&id=204

I mean that I used ledwalker to make a project, file .led

So, what is in that file?

how can i make my arduino can play that file

You can’t make it “play that file”. You can make it open that file, and read the data in the file. If you can make sense of the data, you can set digital pins high or low as appropriate, for as long as required.
