How to (simply) sync hard drives/folders from two different PCs?

[Just Visiting]

I am in the process of slowly migrating one my large folders with thousands of files from my legacy W7 PC to a new laptop. At the moment, I wish to keep both folders on both drives and then merge the folders back and forth as necessary.

Is there a simple function I can use to scan both folders (the one my laptop and the one on my desktop) when I copy them over to a temporary directly on each PC and show me only the most recent ones? Or perhaps there's an even simpler approach you can recommend? For example. The main folder is called MYdocuments on Laptop and the other is called the same on my PC. I use a USB drive to copy the folder onto and then would run Everything to compare the differences.

In other words, if my large directory or PC is called Dell has been modified on another PC, but needs to be merged into the same directory onto another PC called ASUS, that's really all I want. Any files which have been deleted, say from, Dell would have more priority over the files that still remain on ASUS. They would also be deleted [automatically] on ASUS as part of the process. At least that's what I need.

I have played around with the GUI and the results have given me sore eyes and a headache. I hope there is a simple "turn-key" solution to accomplish what I'm looking for. Thanks

How turn-key do you expect it to get?
Whatever sync application you use, including FreeFileSync (FFS), you will need to specify the two locations to be synced (in FFS the left and right base location) and the sync method, which in your case needs to be the FFS Two-way sync variant.
And obviously you need the enable your local machine (the one you are running FFS on) to have file-access to the remote folders to be synced.
