In macOS, when you move a file from a USB flash drive to Trash, macOS creates a hidden .TRASHES folder and places a copy of the file in that folder. This allows you to restore the file if necessary. When you empty your Trash while the USB flash drive is connected to your computer, macOS automatically deletes all files in the drive's .TRASHES folder.
