hiya. this guide helped me get started so i will share a little trick with you guys who may not be so computer savvy.
when working with the command line, batch files can save you alot of time and effort. here is a simple batch file that will save alot of time with the texture packer.
first of all open your start menu, and search for folder options under the search for files bar and hit enter. in the window that pops up, switch to the "view" tab. here, you want uncheck the option to hide known file types. for a while now consumer windows sets this on by default to help save people from accidentally changing a file type, but we will need to do just that here in a second. hit ok.
open your texture unpacker directory, right click in empty space, hover over "new" and select text document. this will create an unnamed txt file. right click and rename, give it any name you want, but change the .txt, to .bat. windows will promt you to confirm that you want to change the file type, hit ok.
once again, right click the file, and select edit. (double clicking on it at this point will try to run the batch) and paste this in there:
file>save, or simply CTRL-S, and close the file.
whenever you run this batch, it will open a CMD window already pointing to the directory that the batch file resides in. from here you can right click and send to desktop as a shortcut if you wish.
have fun
