Thanks for the link, that guide seems much more straight forward, just a quick question though. I have already gone through the process of optimizing the .dds files (as part of the other guides instruction) but I didn't do it the way it is shown in the guide you linked, I just located the .dds files and clicked 'process' so I missed out these steps;
Check the "Show Recursive" box below the center text-box.
Click the red [X] to deselect all files.
In the center text box, type "*.dds" and then click [Apply].
Click the green checkmark to select all filtered files.
Clear the center text box and click [Apply].
Do you think it would be ok to still use the already processed files? It would save the tedium of running the program through all of them again.
