how to read the user/guest OS file content for changed files among 2 VM snapshots

Hi All,

I am trying to find a way to read the file content just for the changed user files in a VM.

Snapshots are supposed to be incremental once they implement Copy on Write, is this accurate? However, when I mount the vmdk of a snaphot, the whole original vmdk is mounted, not just the changed files.

Is there a way to identify the OS/user changed files and somehow mount the delta disk file to read the file content?

Thank you.
