In order to select multiple files for an operation such as copying, moving or deleting in Windows Explorer, you generally use the keyboard and the mouse, Ctrl-clicking every file you want to select.
But if you’re mouse-centric, there’s a way to select multiple files in Windows 7 using only your mouse, via check boxes. To do it:
1. In Windows Explorer, click Organize, and then select “Folder and search options.”
2. Click the View tab.
3. In Advanced Settings, scroll down and check the box next to “Use check boxes to select items.” Click OK.
4. From now on, when you hover your mouse over a file in Windows Explorer, a check box will appear next to it; click it to select the file. Once a file is selected, the checked box remains next to it; if you uncheck it, the box will disappear when you move your mouse away.
