Oh, boy, if you saw how many webpages I have bookmarked that I will likely never open again despite a well thought out system of well labeled folders and subfolders you’d be amazed. And I had a good reason to booksmark every single one of those!
When I buy a new computer the folders are copied as they were, but they don’t show the webpage’s icon until you open them the first time again, otherwise there is a placeholder symbol that looks like a world map. Thus I know at a glance how many I did not open since I bought my last computer about five years ago. Way more than half of them.
But it has saved us a lot of toner and paper, that is for sure.
Still one of our classic points of contention is that I want to keep things (with good reason!) and she wants to clean house and throw stuff away (for no reason at all! We have plenty of space!!). She mostly ends up winning in the material world, I keep my stuff in the digital realm.
