I want to be able to do this:
let's say I have two equal categories: books and movies.
I at the same time have two other equal categories: children's and fantasy.
I want to be able to basically just give a new file properties, for example Lord of the Rings ebook will end up belonging to both book and fantasy, while Harry Potter ebook might belong to both book, fantasy and children's.
I then want some kind of searchable library. Where if I search for books, I will have all the files that belong to children's in one folder, and fantasy in another, and if I search for children's I want all books in one folder, and movies in the other, and possibly fantasy in a third.
I want to be able to assign many of these properties to a document and search it through. I have great problems with sorting out my library of documents, books, movies, notes, ideas, reminders, etc and make it easy to find, because one day I might want to look at all my books, and the next day I might want to look at a specific field of study, and find the books for that topic there, together with my notes, other documents, video clips etc. I know that computationally this problem should be trivial, but I don't know of any software that can do it.
If in this software there would be easy ways to make standard folders etc, that would be great. For example the first thing I always do when I start a new topic is to put a document called links in there. All this seems very inefficient, time consuming, and hopefully unnecessary. Thanks in advance
