The case: need software to sync folders on USB thumb drive

A USB flash drive, also known as a USB stick, USB thumb drive or pen drive, is the most frequently-used portable storage device. We not only use it to store important files or data backups but also use it to create Windows Recovery Environment USB for system repair.

It is quite common to sync files between computer and flash drive. Here is a real case from the forum:

“Hi, I carry a USB drive that contains the data I use for work. When I get to work, I plug in the USB and work from the folders on it. Then, when I get home I copy the contents to my PC as a backup.
Is there software available that will sync the contents of the USB drive to my PC on demand?”

Although you can transfer files between computer and flash drive through copy and paste, it is a tedious work to copy files manually each time they get changed. What you need is specialized USB flash drive sync software to help you sync files automatically.

  • Options: you can write a comment for your sync task so that you can figure out the specific sync contents; you can also enable email notification here.

  • Don’t modify the source folder name after doing file sync, or the program cannot synchronize it anymore.

  • AOMEI Backupper currently only supports one-way sync from the source folder to the destination folder. If you want to auto copy files from PC to USB, just create another sync task.
