I want to copy the attachment of QQ mailbox to USB flash drive. Let me introduce it. The method is as follows.

First log in to the mailbox and log in with the computer. Go to your email, find the email with the attachment, and then click the attachment to download it. Remember to save it to your desktop or where you often download it. Just remember this download directory.

Then plug in your USB flash drive and start copying.

Right-click the downloaded file, select Copy, then open my computer, double-click to open your USB flash drive, right-click the blank space of the USB flash drive, and select Copy.

So your files can be copied to a USB flash drive,

thank you

Hope to adopt
