Auto Bulk Read (previously called "Automatic Bulk Read") is a unique mode for Production Server that allows master discs to be read and stored as images on your hard drive. Settings can be changed to allow you to modify image naming, format, etc. You can also extract files and folders from ISO9660 images. Filters can even be added to extract specific file formats! (e.g., .pdf, .btw, .txt)
