    What you'll need:
    -A working virtual machine in its own folder (can be from just about any virtualization or emulation program)

    To Create A Snapshot
    1. Move the virtual machine folder out of its current location and put it on the desktop or somewhere it can be easily located. Make sure you remember the original location of the folder.
    2. Open VirtualFolders and press the "New..." button.
    3. Select "Create from Folder" and put the maximum size of the virtual machine in the size field (you might want to have a little extra space for the configuration files and ram save states, so if you have a 32 GB virtual disk and 1 GB of ram allocated for the VM, put (32 (virtual disk size) + 1 (ram allocated to VM)) + 1 (extra space for configuration files, etc.) = 34 GB in the size field).
    4. Give the virtual machine a name and press OK. Locate the virtual machine folder. Set the location and name of the virtual folder to the original location and name of the virtual machine folder.
    5. Wait, it could take a few minutes for the virtual folder to show up on the list.
    6. Select the virtual folder and press "New...".
    7. Select "Create Modifications to Selection". Put in a name and press OK. When asked for a virtual folder location and name, just go with the default.
    8. Wait for it to show up on the list.
    9. To use this snapshot, select it and press mount.
    10. Repeat steps 6 through 9 to create additional snapshots. You may have to edit the path and configuration of the snapshot if you want to use more than one snapshot at once.

    Sorry, due to a small bug in VirtualFolders (it will be corrected new release) the instructions I posted initally did not work. I've made a small change to the instructions and edited it into the original post, the new instructions should work.

    I've fixed the bug in VirtualFolders that had prevented the original instructions I posted from working. :) Now it isn't necessary for the virtual folder of the VM to be created as read-only, so you can leave that unchecked. Of course, you still have the option of checking it and even compressing your VM if you want.
