Sorry if I wasn't quite clear with what I wanted.
Although it looks like the issue can be solved with cloning the VM's virtual disk to the second datastore, there may be an easier way.
What I need is the file listing for the files in the VM's folder, as well as one for all of the other VM's folders/files on the filled up (first) datastore.
The reason why you datastore fills up, is that you seem to keep multiple snapshots for a long time. Please remember that each single snapshot can grow up to its parent virtual disk's provisioned size. Also keep in mind that snapshots are not a replacement for backups!
