Move or copy files to subfolders
You can use Windows Explorer to move or copy a file by dragging the file icon to a folder. When you have All Folders displayed on the left side of the window, it's easy to drag a file to a different folder.
If the folder you want isn't visible because the folder it's in is not expanded, here's a trick that will save you time and frustration.
- Drag the file icon to the collapsed (unexpanded) folder, and hold it there for a few seconds.
- The folder automatically expands and you can drop the file into the folder you want.
