How to Sync Two Folders in Windows

In this post, we will go through some of the ways you can use to sync multiple folders in Windows 10 from one drive to another drive (internal or external). It’s easy and just takes a  few clicks after selecting a source and destination folders.

You can use it setup real-time two way sync between your laptop and external hard drive, so you don’t have to worry about, is my important folders files are synced with an external hard drive or not.

Like we synced our important software setup files and movies with an external hard drive so if anything happens to our main hard drive we have important software backed up in our external hard drive.


  • No manual intervention to check both folders have updated content or not,
  • Customizable Sync options, You decide when to delete when not,
  • Works as a backup

It can be done automatically by just selecting two folders and you can add new files to one folder it will be copied to another folder without any duplicate files.
