Just want to say a massive ‘Thank You’ to Jim for they great help with synking, (see DevonThink Pro Office & Synk to Dropbox) his response was to send me an instruction sheet that enabled me to synk with ease. I have said it before and no doubt will do so again but all the guys at DevonThink, especially Jim, provide the best after-sales service and help that I have ever experienced with any software company. 
Thanks for the kind words. It’s very appreciated.
No problem.
Maybe you could explain the sync procedure here, Allsop?
