In most cases you take the files that are to go on the cd or dvd and zip them up (winzip.com). You may also make a DVD .iso image file (does not need to be zipped up).

Once you have that zip file, or maybe your DVD .iso file, you upload that to your web server, the free public FTP folder, or the TrepStar Project.
Upload your artwork .jpg files directly to the TrepStar project. Do this for the graphic that's to be printed on the disc and any other printed graphics (such as dvd amaray case overwrap, or cd case 2 panel or back tray images. .JPG only)
From within the TrepStar.com project management area (www.TrepStar.com) you then specify the download url to your files (such as http://www.yourcompany.com/files/cd1.zip or .iso etc.).
Once your project is approved, you may click the order button to create a new order. At that time, we download the files (usually only once) and burn them to the disc.
