Redirecting Organizer to an External Hard Drive

I’ve been using Photoshop for years to keep and organize my photos.  I recently moved from one laptop to another.  I backed up on the old system and restored on the new.  All the photos were in folders based on dates.  I had tags and names as well.

When all restored, I found I lost many photos.  The photos remaining are on the C drive of the laptop.  Photoshop has all the thumbnails.  Some with photos, some “missing,” and some on a DVD or other device.

I always thought Photoshop actually imported the photos.  Apparently, it sometimes leaves them on the USB drive, DVD, or even phone.  I went back to every old device, DVD, and backup to find as many as I could.  They are now all stored on an external hard drive.

I now want to redirect Photoshop Organizer to the external hard drive.  But I want all the date based folders, tags, and names.  If successful I will delete all the photos on the C drive.

Any suggestions?
