DTE, which stands for Direct to Edit, is a fancy way of saying that you can edit a file directly without having to copy or move it somewhere else first. Think of it like having a special magic wand that you can use to change things in a file right where they are, without having to pick them up and move them to a new spot.
This is really helpful when you're working with files that you want to change or update quickly, without having to mess around with copying and pasting them all the time. Instead, you can just open up the file, make the changes you need, and then save it right where it is. This is sort of like having a big invisible eraser that you can use to fix things right in the middle of a document, without anyone ever knowing you were there.
Overall, DTE is a great tool for people who work with files a lot and need to make changes quickly and efficiently. It saves time and effort, and makes it easy to work with files without having to constantly juggle them between different locations.
