Yep, that's because once you start the snapshot, all changes to the guest go into the snapshot, which can make them extremely huge. I bet there was a significant reduction in space used on your SAN when you collapsed the snapshot.

If you remove them, they get incorporated into the base image. You will generally need to do this before moving them. Maintaining snapshots for any length of time in a vmware environment really isn't a good practice.

I'm guessing you don't want to do this in case you need to rollback the server to a previous snapshot?
