Class work: Search vs. Sort

To my understanding as we collect files on our computer, we are putting them in the folders, well, when we try to decide whether it is better to keep files miscellaneous and just search for the files, or of organize them into folders and sorting the files.  Well, I think we could never have just ONE thing.  We should be able to have that rigid hierarchy, but sometimes, it is easier to be have the ability to find a file by keywords instead of looking for that “one” folder somewhere on your computer.
