In Create ISO from CDROM, what is ASPI or FILE means?
In ASPI mode, you will get an ISO file with exactly the same structure as the original CD-ROM disc, with bootable information, and all other internal disc format. If you burn this CD image file to a disc, you get a exactly same disc as the original. In FILE mode, WinISO will create a new ISO file by copy all files and directories on the disc. This ISO file will use WinISOs default format. If disc is bootable, then the bootable information will be lost.
