Lr has no auto-structuring mechanism, except during import. So if your files are already imported, then you can't auto-restructure (into different file-system hierarchy), without re-importing which may not be such a good idea. Of course you can manually create folders and move files into them if you want to.
That said, there have been no changes to Lightroom in this regard for a long time now, so maybe if you explain more about what's happening or not happening, it could be something simple..
Screenshots and a concerted effort to be specific and use correct terminology may help.
Thanks so much for the quick response.
started in LR4 in PC
Moved to Mac and OSX with LR5 (Mac Pro Book retina with solid state drive
I had my PC original photos on an external PC drive that was filling up and
only could be red by mac but not written.
Just bought a 1tb drive and formated it for Mac
Moved through finder all photos and LR catalogs from PC 640gig drive to new
mac formated 1tb and then imported them which did not take a long time and
did not bring originals into the mac. This was a new catalogue. I still
have the old one and the files on the PC external drive.
LR finds and displays these originals (a mix of raw and jpegs with a few
tifs. A 14 year collection, perhaps 18,000 images) but the list is not
subdivided in any way, just one large group of photos in date taken
sequence. The old catalogue was subdivided by day, month, year. I may
have created duplicates but have not checked. I had a backup copy of some
lost photos which imported.
My goal is to have all photos broken out by date. I must retain edited
results and would like to maintain meta data.
Is this enough info? What else would you like?
Are you looking at the old Catalog on your new Mac or is a New Catalog we're discussing?
As Rob has already mentioned LR doesn't have any auto-date structure mechanism other than at time of import so I suspect that the format you liked in your old catalog was as a result of the import settings.
You should be able to transfer the old catalog across to the new Mac if you haven't already done so. Once you've done this we can re-link the files to the correct location in the catalog if the drive designations are not the same as they were on your old system.
Yes Mock and Rob I have the old catalogue with date folders in the Mac but
it is pointing to my to small old read only external drive. I want to move
these originals to my new 1tb Mac based external drive
What is the best way to do this with out loosing info.
Pretty much just what NicHamilton said: it's a simple matter to re-link moved photos to an existing catalog - no need to create a new catalog, or re-import...
I'm assuming it will look like it did before afterward, if not, then let's talk..
