Compact Database

Have the design team made any progress with adding this feature?
It is now 2 years since they spoke about it. I now have an eM Client folder of about 5.5Gb but I know that if it was properly compacted it would be a small fraction of that size because most emails end up being deleted after a few weeks. I have run the compact tool on the previous mailing but it does not work, my eM Client folder grew by more than 1Gb after running it.
I wonder if the design team even understand the concept of Compacting? It releases the disk space left by deleted mails. Very important if you are using an SSD and space is of a premium.
Or does anyone know of a program that will compact the mail_data.dat file?
