Moving Devonthink from one Mac to another

I’m moving ‘house’ from an iMac to a Powerbook and would appreciate some help.

I’ve moved the DT application itself, but as for what I thought might be a DT database, looking under Library/Application Support/DEVONthink/DEVONthink-1.database I see I have four databases (and also a crashlog), and each database is duplicated with a slightly smaller file of similar name as e.g.
DEVONthink-1.database
and
DEVONthink-1database~

DT is working fine but the above looks untidy, so before I move the whole lot over, do I need to do some house keeping. Have I been doing something wrong?

Thanks,

Michael

A DEVONthink database needs all four files. Files with a “~” character at the end are just backups. You may delete them but we don’t recommend this.
