gBurner Virtual Drive vs WinISO

gBurner Virtual Drive is a free Windows utility for creating virtual CD/DVD drives and accessing disc images without burning them to physical discs. It can create up to 16 virtual drives and supports formats including ISO, GBI/GBP, DAA, NRG, MDF/MDS, BIN/CUE, UIF, ISZ, DMG, IMG, and VCD. To mount an image, users open the virtual-drive tray menu, choose the mount command, select an image, and confirm. The same menu provides an unmount command. The download page lists Windows support from version 98 through Windows 11, including 32-bit and 64-bit editions. The free utility is listed at free and is described as free for personal and business use. However, the download comparison identifies mounting an image file to a virtual drive as a gBurner Pro feature rather than a gBurner Free feature. Pro costs $39.95, paid once. The maker says game and program images can run at over 200 times the speed of a conventional CD/DVD-ROM.
