About : Folder2Iso just creates an iso from any kind of folder (with the subfolders).
Its a GUI of mkisofs.
No need of installation , really small exe.
Some of you can say : "What is the point of this tool? Seems useless."
Well dvddecrypter/imgburn can burn cd/dvd for free so if you make an iso easily you can burn your movies on cds/dvd for free. It is also usefull for the dvd2avi guide ...
So : dvddecrypter/imgburn + Folder2Iso...
