Do you have ISO or other disc image files in your system and want to mount them in Windows?
WinCDEmu is a freeware which makes mounting CD/DVD images simple. Double-click on an image file in Windows Explorer and a new drive letter with the mounted image will appear. You can mount as many images as you want at the same time, and you don't need to reserve drive letters when nothing is mounted.
WinCDEmu supports ISO, CUE, NRG, MDS/MDF, CCD, IMG formats and runs on all Windows versions from WinXP to Win7.
To unmount an image, double-click the corresponding file in Explorer again, or simply eject the corresponding CD drive using the context menu.
WinCDEmu is an open-source software and comes with English, Russian, Japanese, Italian, French, German, Greek, Romanian, Spanish, Portuguese, Norwegian, Dutch and Traditional Chinese languages.
It also comes in a portable version which is a special build of WinCDEmu that does not need any installation and can be used out-of-the-box.
