OSFMount is a unusually powerful tool for mounting disk images in Windows with a drive letter.

If you've downloaded an ISO file, for instance, this means you don't have to burn it to a blank disc to browse its contents. Just use OSFMount and it'll appear in Windows as a new drive, so you can view the image in Explorer and extract whatever files you might need.

OSFMount doesn't just support ISO files, though. Other formats it can mount include IMG, DD, BIN, 00n, NRG, SDI, AFF, AFM, AFD, and even VMWare's VMDK.

And that's not all. The program can also create a RAM disk, so for instance you could allocate 1GB to a new virtual drive V:. This may help with performance of some programs, as RAM disks are extremely fast. It also has privacy advantages (tell a browser to store its internet history there and it'll disappear when you reboot). And you can even use OSFMount to save the contents of your disk in a variety of image formats, including ISO, BIN, IMG and DD.

OSFMount 1.5.1013 brings these changes:

Columns and main window are now resizable
Added "DEBUGMODE" command line parameter to OSFMount (GUI) for debug logging
Added "File system (detected)" column in the mounted drive list (for file systems unsupported by OS)
APM partition scheme is now supported, along with more robust partition detection
