To format a USB flash drive (also known as a U disk), you can follow these steps:

1. Connect the USB flash drive to your computer.
2. Open "This PC" or "My Computer" on Windows, or Finder on Mac.
3. Right-click on the USB flash drive and select "Format" from the dropdown menu.
4. Choose the file system you want to use (such as FAT32, exFAT, or NTFS).
5. Enter a name for the USB flash drive if desired.
6. Click on the "Start" or "Format" button to begin the formatting process.
