It's easy, and yet it's nowhere to be found in the official Windows manual. After you've got File Manager looking the way you want it, hold down one of the Shift keys and double-click the Close button at the upper left. To force File Manager's windows to fill out the overall space within File Manager properly, open the Window menu, hold down the Shift key and choose Tile. Be sure to save this new setting using the technique above. File Manager makes copying, moving and deleting items very easy.
File operations work in a simple way.
This deceptively easy method hides a big danger, however. File Manager's notion of copying may not be the same as yours, and you will sometimes find that File Manager actually moves items instead of copying them. To force File Manager to copy an item, hold down the Control key while dragging. Deleting files and folders is simple. Highlight the file or folder you want to delete, then press the Delete key.
