I know a lot of you probably never get to experience this part of Windows, but I have a touchscreen laptop for work, and I love this feature of clicking boxes. I know most just highlight or hold down the ctrl button then click, when you want to delete or copy certain files.
@W1zzard Thought you might find this interesting since you probably never get to see the touchscreen features of windows with your professional setup.
The checkboxes though is just an easy and lazy way to do it, quite handy. Even on non-touchscreen use cases I find it comes in handy. Especially when holding and dragging an area you want to copy and paste is not possible because the files you want are separated by other files, etc. Again you can just hold down ctrl and click, but this is the lazy way. lol
There is a little white box next to each file as seen by the white box to the left of Name in the below picture.
