If I can find a way, I'll be able to click on or maybe search a tag, which will result in all the folders with said tag appearing. I'd even settle for a just a tag-sorting function. It should be clear that I'd like to be able to tag my folders specifically, not just the files within a folder. Whether it works with Windows or is standalone, I don't care. I just want to tag folders.
If anyone is aware of any preferably-freeware application out there that can accomplish this, please let me know.
