Never mind, I think I found it.

I finally am getting around to organizing my digital photos, I have everything sorted by folders named according to the yyyy-mm and photos named yyyy-mm-dd.extension and intend, and have already started, tagging photos based on occasion, where I used folders for that purpose earlier. I was able to tag multiple photos easily within the Windows 7 Explorer. The thing is, I haven't tagged photos in a while, and I don't see any obvious way to view by tag in Explorer or Google drive. In Picasa and probably in Windows I can do a search by tag and find photos, leading me to think tagging is only good for searches. Is there a basic photo organizer that just lists tags on the side like folders so anyone can just browse the tags? It seems like I just made everything harder to find for everyone.
