I keep most of my recipes online under folders such as Air Fryer recipes, Breads, muffins, rolls recipes, pies, cakes recipes, instant pot recipes and so on. I also have binders upstairs in the cabinet and keep those recipes I use a lot with dividers the same as on my PC. I put all my printed recipes in plastic sleeves to keep them clean.
By keeping them on the PC, if I can't remember where to find the recipe I'm looking for, then I just print it up again. Plus my sister and friends from time to time want one of my recipes so I can just print it up or send it to them as I keep them in PDF format.
I have one binder just for Instant Pot recipes and one folder in the Dessert Binder just for cheesecake recipes as I make a lot of them since making my 1st one in the Instant Pot and found out just how easy it was to make.
