Find it difficult if you need to highlight multiple files at once via Ctrl + Shift and then stuffing it up time and time again? Enabling the check box feature would be useful.
Navigate to Start and type Folder options in the search bar. Click on Folder Options to open it.
The Folder Options dialog box appears. Navigate to View tab, scroll down under Advanced Settings and tick the box Use check boxes to select items.
You will notice a checkbox next to every item you want to select.
If you want to select all files or all folders tick the box under the menu bar.
