WinISO Help - Make ISO from CDROM

How to create an ISO from a CD-ROM Disc

Press "F6", or click 'Make ISO From CDROM' in 'Actions' menu. The "Create ISO" dialog will pop-up.

Select your CD-ROM drive that holds the CD-ROM disc, and enter in the destination ISO file name. Now you can click the 'Make' button to begin making an ISO file.

What's the difference between 'ASPI' and 'File' mode?
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 the disc is bootable, then the bootable information will be lost.
