Open Windows Explorer by pressing Win+E on your keyboard. Select any one of the folders or files you want to select. Now press the Ctrl key and keep selecting the files/folders you want to select.

If you already have a program on your desktop and want to open a second or multiple instances of the same application in Windows 11/10, here's the trick!

Go to the folder you want to open upon launching File Explorer, click the address bar, and copy the path. Replace PATH1 on line 8 with the first folder's address.
