gBurner Virtual Drive vs SysTools ISO Creator

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.

SysTools ISO Creator creates and edits ISO files from local files and folders on Windows and macOS. It supports ISO 9660, UDF, and Rock Ridge formats, and can make bootable images from system files or installation folders that contain the necessary files. When building an ISO, it preserves folder structure, file names, and paths. The software is described as offline: it does not require an internet connection or upload data to a cloud or server. A real-time ViewLog record tracks activity and can produce a report of actions. The free version limits handling large ISO files and saving edited or bootable ISOs. The Full Version costs 29.00 USD once and removes those limits. Windows needs 100 MB of disk space, 4 GB RAM, and .NET Framework 4.5 or above; the product page says to run it as administrator on Windows 10 and 11. The Mac version needs 200 MB of disk space and 4 GB RAM, supports Intel and Apple Silicon M1, and requires the system region to be United States and the language to be English. Disc burning is not supported.
