How to access VMWare guest OS file system from host?

I have a Ubuntu guest OS ruing on VMWare Workstation 12 on a Windows 10 host machine. Recently the guest OS became unbootable. I have a snapshot from a couple weeks ago, but I wish to recover the files in the unbootable VM, and so far I have been unable to boot from a Live DVD. Is there any way to access the guest OS, eg. some tool to mount the file system on Windows 10 host machine?

Thanks!
