Yesterday I added a folder containing 16gb of video training files. Today I determined that it would be an unnecessary burden on my back up system (I keep a rotation of seven days of backups).
The addition of the videos moved the db file size from around 18 to 34 gb. When moved the folder out (I dragged and dropped it to my desktop) the database remained at 34gb. I quit DT and got the same answer. I then reboot and still 34gb. Lastly I did a “rebuild database”, rebooted and still 34 gb???
