I take it from your post that you are not using Lightroom yet. You are likely to get many opinions on your questions. Hello. Right now I'm consolidating tens of thousands of photos from external drives, internal drive, SD Cards, Google Photo. Tens of thousands are not a particularly large number. Many Lighroom (LR) users have more than 100K images. I have about 186K referenced in my LR catalog. The catalog is a database of information about each image that has been IMPORTED into LR. That includes all the information that the camera puts in the image file and all the processing and file location information. The image files are not "in" the catalog. LR just keeps track of where the files are on your hard drives (local and network) It's a time suck, so I want to get it right. I could use some advice: How much time would you invest creating/managing a folder structure on hard drive? Depending on your definition of "time suck", getting your image file structure set up properly is a very important thing to do. Most of my photos are in some kind of folder structure, but a significant number are not. If I understand correctly... All of your photo image files are in some kind of folder structure already, except possibly those that are in the root of the drive which would be "C:" in Windows or "Macintosh Hard Drive" in Apple OSX Lightroom will create a catalogue of my photos Yes, as described above The catalogue will have pointers to the file locations-- so I shouldn't ever move them Yes, but there are other reasons to have all of your image files in one top level folder as in C:\ Xxxxx Photos. Replace the Xs with your name. You can and should move the files in LR, except for very large folders. Do not move the files outside of LR until you know what you are doing and can tell LR how to find them again. I can organize by creating virtual "folders" within Lightroom "Virtual Folders" in LR terminology are "Collections". Collections are very useful, but your folder structure will be recorded in LR before you use Collections. There are various apps/services that can work with the folder structure in Lightroom Not in the sense that they will help with your file organization. Someone will probably chime in with some plug in here but you should learn the basics of LR first. If that's the case, which of these makes the most sense? Spend hours looking at every photo to create folder structure on drive. Do this before creating LR catalogue. My answer to that is yes. It depends on how detail oriented you are. If you do that, as I said above, put all your images into subfolders of the Master Xxxx Photos folder Dump all my existing folders and "orphan" photos into one big folder-- then use LR folders to manage This is a workable solution. One images and folders have been Imported into LR, you can reorganize them in LR as long as you are not trying to do this to folders with masssive (1000s) of photos. Get rid of existing folder structure completely. Everything goes in one big folder on drive, and I manage using LR folders. A number of LR users will probably recommend this. I find it to be a big mess, because I organize my image folders like this: C:/Ken Photos/2017-11-22-LaurensBirthday. By doing that, I can find and access all my image folders outside of LR to find JPGs, etc for emailing or buring to CDs, etc. This works well for me, I have 6TB of images on 2 4TB drives which LR handles fine. Something else I'm not seeing This subject is kind of like religion, you may get many suggestions. Note: The big advantage of having all you photo image files under one master folder is for backing those images up. It also saves a lot of work when you upgrade to a different computer or want to move all those files to a new hard drive.
