How to Use a USB Flash Drive on a Windows Computer

A USB flash drive — also called a thumb drive, memory stick, or USB stick — is a small, portable storage device about the size of your thumb. You plug it into a USB port on your computer to store files, move documents between computers, or keep a backup copy of important things.

Windows computers have USB ports on the side or back (older computers) or on the front. When you plug in a flash drive, Windows will recognize it automatically and assign it a letter, like "D:" or "E:". You can then open it in File Explorer just like any folder on your computer.

Flash drives are great for: - Backing up family photos so you have a copy in case your computer breaks - Moving a file from one computer to another at home or at the library - Giving someone a document without using email - Storing a spare copy of important documents like tax returns or medical records

A typical flash drive today holds 32GB or 64GB of storage — enough for thousands of documents and photos. You can buy one at any pharmacy, office supply store, or department store for about ten dollars.

One important habit: always "eject" the flash drive before pulling it out. This tells Windows to finish saving any files and helps prevent data loss or a corrupted drive.
