Do I have to delete the files in the recently uploaded area?

If a file that I uploaded and then put into a folder, for example, dwarffighter.png put into fighter folder, is for some reason showing up in my recently uploaded folder, and I click on delete it, it says that it will remove it from the game for me. When I put the file from the recently uploaded into a folder, that automatically adds it to my library, right? Why do I have a long list of stuff hanging out in my recently uploaded area, despite clicking on the "filter out items already in your library" button? Thanks for any help. 

Those are items that are unfiled. DO NOT REMOVE THEM, unless you want to completely delete them. When you put an image into a folder, you are actually giving the image a tag. Nothing really gets "moved" anywhere. Once all images are moved into folders, clicking on that button will hide everything. It is my experience that most people don't bother filing, though.

There should be a little double box icon next to the Recently Uploaded name. Click on it and it hides the images you have filed.  I always file my images as soon as I upload them. Keeping your Image Library organized is worthwhile in my experience. 

This is what I do with images that I upload. Upload images and have empty folders created. Drag the images to their folders Then doubleclick on the two squares to the right side which makes the recent uploads disappear. It helps me keep track of what I have uploaded so it reduces any chance of duplicates. If you double click on one of the images, it will open your library menu where you can tag the images for easier search also.

I have uploaded 1200 images and organizing by type is not perfect; by adventure, also not perfect, by campaign... i reuse maps and items a lot... so also not perfect. And maintaining that tree of images by hand.... requires a lot of scrolling while dragging... it's a painful exercise.  So my genuine question: what's the right way?

That's not something we can answer for you. I have my Art Library, built up since 2014, organised into Scenery, Avatar, Faceplate, Props, etc., at the top level. Under Scenery I have it organised into the Adventure where I sourced the map. Under Avatar and Faceplate I have it organised into Settings: Fantasy, Cthulhu, etc.,  I organised my top-down tokens using folders named Aves, Reptilia, Carnivora, Perissodactyla, etc., and that works just fine. You can decide for yourself if owlbears are in Aves or Carnivora. You can put them in both. You can also Tag your Art Library based on what's in the picture. So I've tagged maps with Rocks, Trees, Roads, etc., and tokens with Swords, Shields, Wands, etc.,

For a library like yours', the best way would be to tag each image, and then search by tags when you need them. You can add as many tags as you like to an image, so they can be in multiple 'collections'.  The actual work of tagging 1200 images isnt going to be fun though.
