There are many benefits to using folders when working with lots of files. Here are a few examples:
- You can use folders to sort your files by type, almost like drawers in a desk, so you might have folders for Music, Photographs, Documents, etc.
- You can use folders to group files together into a specific group. For example in your Photographs folder you might have a folder titled BirthdayPhotographs for all the photographs from your birthday.
- As in the example above you can nest folders to create sub-categories. Documents might include folders for Homework, Stories, Poems
- Folders can have different permissions applied to them, allowing you to keep personal files in a private folder only you can access, or secret files in a folder that doesn't show up in the normal list of folders!
