If you want to select more than one file in the Windows Explorer, you have to press the Ctrl or Shift keys and then click the files you want to select. But if you want to simplify the process of multiple file selection, then you can use checkboxes to select multiple items in a folder. Here is how :
- Open any folder. Click on Organize → Folder and Search Options as shown
- This would open the Folder Options window. Select the View tab by clicking on it. In the options list, check the checkbox labeled Use check boxes to select items as shown
- Click OK to save the settings.
Now when you hover mouse over any item (file or subfolder) in a folder, you would see a checkbox. Clicking inside the checkbox selects the item. If you click in a empty area in a folder, all the items are de-selected. If you click on a file(or folder) icon instead of the checkbox, then all the items are de-selected.
