Hi William, please do this:
Plug the flash drive into a USB port on your computer. Windows 10 will assign it a drive letter, similar to your C: drive.
The letter assigned depends on your hardware but will most likely be E: or F:
Click the start button and open File Explorer
Scroll through the items on the left side of the File Explorer window and locate your flash drive
and left-click on it one time.
You will then see the contents (files and folders) of the flash drive on the right side of the screen.
Right-click on any file and from the menu select Copy (this moves the file to system memory, temporarily)
You won't see any change on your screen as the file is copied to memory.
Then, go to the folder where you want to place the file. For this example let's assume you want to put the file in your Documents folder.
In File Explorer scroll through the items on the left side of the screen and left click Documents once.
You'll see your files on the right side of the screen. Using your mouse, hold the mouse cursor over an empty space and right-click.
From the menu, select Paste. This will copy the selected file into your Documents folder.
There are many ways to move files around in Windows and I'd like to connect to your PC and show you the various ways it's done.
