Sync folders in two Windows 10 PCs

[shijilt]

I have one desktop and one laptop.
Running Windows 10.
I usually use my desktop, and I use laptop when there is power outage.
Desktop is connected to an ADSL modem using Ethernet.
Laptop uses Ethernet or WiFi, whichever is convenient.
I am able to share folders/files between two PCs.

I want to sync certain folders using the same LAN, how ?
I dont want to use cloud - because, here internet is slower than you think..
Cant sync the hole PC(s), because Desktop has 1.5TB (SSD+HDD+HDD)storage and laptop has only 250GB (SSD)

You can download any number of free file-syncing utilities.

Share the folders to be synced and set up the schedule.

Generally all of the syncing utilities do much the same thing. The differences are in the User Interface, available configuration options, etc.... May present ads, nagware, or impact system performance. May take some downloading and testing for you identify a suitable product.

I use FreeFile Sync and have tried others from time to time.

Just be sure that you download the free software or full version trials directly from the manufacturer's website. Look at the Support related FAQs and Forums beforehand. And the User Guide/Manuals if online. Look for end user reviews. Doing so will help you understand how the program works, the requirements, and the configuration options available to you.

Choose and test.
