Can you be more specific on "before and after?" Is that before processing and straight from drone and after processing you are looking for? If so, the
@Phantomrain.org has a good suggestion.
I use Lightroom as well and I import the files, then save to a separate folder in same directory as the originals - typically Lightroom names it Export, but you can name it anything you want. I create my new folders with date of pictures / name of location before moving my files from the SD cards to my PC. Since I shoot both drone and DSLR, I move the main folder - for my Nikon it's NCD100 or something like that and so it's a subdirectory under the date / name folder. If I want to keep the photo's separate, again in Lightroom I just change the "save to folder" name.
There are some programs that do allow you to find and catalog files, but I've never used one - sorry. There are some "photo sticks" I've seen advertised that also seem to catalog the photo's - probably more so by date or naming convention, but again - don't use them.
