The flash drives nowadays are very easy to use and most do not need any installing. To save files on a flash drive, just insert the flash drive into the USB port. Your computer should automatically detect the new inserted device. Afterwards, open the document you wish to save in the flash drive and select ‘File,’ then ‘Save As.’ Select the drive name (this is your flash drive) and hit save. If you wish to create a backup of multiple files, just go to Windows Explorer, select, and drag your files toward the flash drive.
