Need to Sync Folders between Computers over Network

For teamwork or disaster recovery purposes, many people would like to sync files and folders between computers to keep the data consistent and up-to-date. But how to make it happen?

The usual method is to manually copy folders to a USB drive, and then paste them to the destination computer. Once the source folder is modified, however, you have no choice but to copy the changed files again.

To make things easier, you may want to directly sync folders over network, and I'll introduce you 3 easy methods, so that you don’t need a removable device, any changes in the source folder can be auto-synced to the destination.

Sync Folders Over Internet

Sync Files between Computers via Network Shared Folder

Can you sync files & folders between computers without cloud such as Google Drive and OneDrive? The answer is yes, you don't necessarily need a cloud drive if you only want to sync folders over network.

On Windows PCs, syncing folders over network requires you to create a shared folder and authorize other users in the same LAN to read and write it. If you want to manage the folder sync more flexibly and safely, like synchronizing files between various sources and targets automatically, you could also create sync tasks with file sync tool.

How to create a shared folder for file sync

Step 1. Right-click the folder you want to share, choose Properties.

Step 2. Switch to Sharing tab and click on Share… to give network access to the user groups you want. To allow everyone on the network to access this folder, just choose Everyone and click Add > Share.

Besides, you still can sync folders between computers using cloud drives or offline folder feature.

Among them, the file sync software is the most compatible one, since it not only helps you to sync files automatically but also supports different sync paths, such as shared folders, cloud drives, external devices, etc. Thus, you will always have a copy of the latest files.
