It is real handy for people who do not have a DVD burner but have a DVD they want a copy of... they would split the DVD into even pieces of like 700MB using this program and then burn them each to CDs. My program supports disk sizes of 1.44Mb - 9400Mb. This program will NOT retain the autorun with the spanning (under development). None of my software contains any spyware, adware, any other malicious code. I distribute this as freeware for a reason. No way anything else gets installed to your machine!!! IF YOU TRY THIS AND IT DOES NOT WORK FOR YOU -- EMAIL ME!! Need a custom application, contact me!! Now Supports CD Burning (with XP)!!
