I'm looking forward to your feedback.
Btw., as a sidenote, are you aware that you can access the filesystem
underneath the volume shadow copy as well?
Try this (note the trailing backslash!):
$ cd /proc/sys/Device/HarddiskVolumeShadowCopy1/
$ ls
The only downside is that you can't cd into the root dir of the
shadowcopy by using a ".." expression:
$ cd /proc/sys/Device/HarddiskVolumeShadowCopy1/Users
$ cd ..
/proc/sys/Device/HarddiskVolumeShadowCopy1: Not a directory.
$ cd ../
/proc/sys/Device/HarddiskVolumeShadowCopy1: Not a directory.
Here the path handling strips off the trailing backslash and what's
left is a block device called /proc/sys/Device/HarddiskVolumeShadowCopy1.
With that in mind, it's quite usable, though.
