Database Shrunk in Size?

Before DT3, one of my Db was about 19GB in size. I recently noticed that the same Db is only 1.9GB. Is this possible (like, is DT3 more efficient in storage?)

If I pull that Db out of an old archive, can I give it a different name and open it for comparison?

The required storage is about the same, one difference is that the internal number of metadata backups can’t be customized anymore. Therefore it’s better to compare database properties, not the info in the Finder.

Only after disabling synchronization of this database first, otherwise the old archive would be synchronized to your other computers/devices.

I found the discrepancy… Seems there was a group that had a lot of files that I had at one time.
