Ben,
Thanks for the reply.
I shoot everything to a laptop. This dated folder of RAW files is then copied to my database back at the office for processing.
When I open the folder in Phocus on the desktop, to process the images, I'm seeing a "tree" of folders consisting of yearly folders and, within those, client folders and, within those, job folders.
Occasionally, I have to drill down through Year/Client/Job/Sub-folder, to get at the file I want.
If I then close Phocus and re-open it, the entire tree has closed again, and I'm back looking at just the Yearly folders.
If that can't be changed using a Preference, then it is a brainless design flaw, in my opinion, and should be amended.
