Carl -
We're missing some basic information from you.
1. Have you added all your photo files (I assume they're in My Photos) to your database? You didn't answer my question about this in
https://www.photools.com/community/index.php?topic=6175.msg42630#msg42630. One of your screen shots shows you've added ~ 43,000 images to your database (based on the @All category), but another screen shots show ~ 30,000 in the database and yet another shows 70 in your database. Do you have several databases?
2. How are your image files organized on your computer? I assume they're all under My Photos, but what kind of structure are you using below that? Are your files grouped by date? Or by some other principle (e.g., project or location or camera, etc.)?
3. An Ingest folder is just a temporary spot in your computer for downloading images from your camera (depending on your workflow). Most people download new photos there, then add categories, keywords, captions and other metadata, and after that move them to another location on their computer based on how they organize their files.
You have to move these files manually to a new location when you no longer need them in your Ingest folder, as Mario and JohnZeman have discussed. 4. If you were previously using IMatch 3, can we assume you have already categorized these images? Are you now only concerned with categorizing new files added to your database, or do you still need to categorize all of the images in your database? The answer will help point to the best way to tackle the images.
5. Remember that the Timeline tab automatically shows all your files by date, and the Sample Categories also show the way to use data-driven Categories to show files organized by date. You don't need to do anything new to use these.
If we understand better where you are organizationally and what you want to accomplish, we can provide better help.
