Need to sync folders between drives in Windows

I’d like to sync my Library and desktop folders with an external hard drive. These files change every day and are important to me. I have purchased an external hard drive which is 1 TB in size and should be sufficient. Here is the thing, I want to create a folder in the external drive to store files that be synced from my computer, because I also want to place other data on that drive. I want a fast, secure, user-friendly and free tool for that. What sync tool in Windows should I use to make Windows sync between folders on different drives? Thanks.

There are some situations that you need to perform file or folder synchronization between different data locations. One of the most common ones is sync files to external hard drive to keep data safe. Surely, some users want to sync files to Cloud drives or sync external drive to Cloud to protect data or share files with others. No matter choosing which method, the purpose is to ensure data safe. Then, how do you sync files and folders in Windows 10/7 in simple and secure way?

Windows sync files between folders using SyncToy

SyncToy is a free sync tool that is designed by Microsoft. It helps you sync files and folders between different data locations or devices. SyncToy is a good tool for less experienced computer users due to its graphical user interface. Let’s get to know how to make Windows 10 sync folders between drives with this free tool.

1. Download and install SyncToy as instructed. Launch it.

2. Click on Create New Folder Pair beneath.

Create New Folder Pair

3. Choose the folders you want to sync, the Left Folder for the source folder and the Right Folder for the destination folder. Click Browse to select.

Browse Folders

4. Select sync mode in “What do you want to do?” step. Here are three options available, Synchronize, Echo and Contribute. Get to know them and choose the right one for yourself. For your information, Echo is the most common used one.

Choose Sync Mode

5. Now, name the folder pair to distinguish. Click Finish to exit the wizard and you’ve done.

You can rename and delete existing folder pair.
You can create another new folder pair by repeating above steps if the need ever arises.
You can schedule SyncToy in Windows 10 or Windows 7 with the help of Task Scheduler.

It is very easy to keep Windows sync folders between different drives or on the same drive. Nevertheless, you need to turn to other sync tools in some cases. 

For example, you find SyncToy not copying all files or not syncing subfolders during the process. Or, you want to perform a real-time sync task, not just regular sync mode in Task Scheduler. Further, if you want to sync more than one folder to the same place, you need to create more than one folder pair. Fortunately, you can remedy those regrets in another way.
