Educate a beginner

I installed syncthing today on two Windows 10 laptops: one is the one I use, the other is a backup that I keep in sync in case of emergency.

I have one data folder that I want to sync. I set it not to start after bootup and I want it to sync only at end of day, after I finish work;

So I added the folder other than default and I added the remote folder, which I want ST to keep in sync on the remote computer.

When I load syncthing I get a CMD window open with some things going on.

  1. I have no idea if the folder were set OK.
  2. I have no idea if syncthing works and updates properly
  3. I have no idea how to invoke the cfg screen to make changes
  4. To start syncing do I just loas ST? How do I stop syncing?

IOW, I get no feedback on what I do and what ST does.

I wanted to install via Trayzor, but I am (ON PURPOSE) using an older Windows version that is not supported.

Help would be appreciated. Thanx.

Syncthing is controlled through its Web GUI. Usually it can be reached by entering the address http://localhost:8384 into your browser.

To get rid of the terminal window, you could use a different method for starting, such as the Windows installer package recommended on our download page. It can install Syncthing as a background service, which you can still start and stop manually if desired.

Thanx for responding.

After some trial and error I managed to resolve most of the problems.

I did not see the background option during install. I minimize the terminal window as an icon on the taskbar, which is actually better because I can check the latest activity from time to time.

I think a GUI interface would be a significant improvement, at least for the like of us without a programming background. Pity Trayzor does not work with my version of Windows.

I am seeing all sorts of “not supported in Windows” lines in the terminal window – what do they mean for the user?

Also smtg about port mapping and conflicts that I do not understand.

There are various GUI wrappers available. However most people working on something like that today will not start out worrying about compatibility with very old operating systems. Sorry, you’ll need to move on or switch to a different platform if you want to keep using modern software.

Could maybe tell you if you quoted the actual message.

Don’t worry. Usually meaningless stuff about picky UPnP routers.

Where would I find those wrappers? I would like to check them out, maybe one of them will work.

Once MS started to mess with users’ computers they FORCED me to stick to the first version of Windows 10 that worked. It works and never gave me the troubles that MS imposed. NOBODY will do what they please on my computer. The price is forgo some software.

Smtg about 1pv6 not supported in Windows.


I’m just guessing, but this reminds me of a shortcoming related to UPnP as well. In essence, if it works for you, it works. Don’t worry about the warning message. Or if you’re inclined to dig deeper and understand it, copy the exact log excerpt so we can judge what the problem might be.

That’s what I assumed, but wanted confirmation. Thanks for your help.

If I run into problems I’ll return.

I did not think I would be back so quickly.

Pls bear with me – I am trying to understand how ST works.

I have two identical laptops that each has an identical folder. The intention is that every change on to that folder on my local laptop to be sent (one-way) to the the corresponding folder on my remote laptop.

My understanding of how it’s supposed to work is that whenever I make changes to my “local” folder, ST sends those changes to the remote folder in the background. Do I understand it correctly?

Here are my questions:

  1. For this to take place must both instances to be loaded and running?

  2. 1st attachment shows the GUI on local, 2nd the GUI on remote. Shouldn’t they both show everything up to date – why does one show out of sync? Can you pls clarify this for me?

  3. When I try to access the remote folder I get the message it is not available (3rd attachment). Is this normal? Once the syncing was done, shouldn’t the drive be released to access? Is there anything I need to do to keep the folder accessible?

Not only that, but I cannot close the File explorer windows with this message.


Just some old remains or is OneDrive really involved?

I had to clear some directory mess leftover from when I got rid of OneDrive (actually, you cannot rid yourself of it–they bury it so deep into Windows it’s impossible).

I think I managed to get ST to work correctly – I will have to monitor. But I have a couple of question for my enlightening:

  • Does the browser gui has to be always on for ST to work? If not, how do you bring it up?

  • What happens when one device is off – does ST proceed from the point when it disconnected?

  • And a weird one: last time I installed ST from scratch the Configuration link came with a blank, not ST icon. I installed it several times and this never happened. ???

Welcome here!

No, the browser GUI does not have to be used. The Syncthing executable has to run. Nothing else.


Ok don’t know, and quite frankly I don’t understand your question. Maybe others can help.


Never mind – the icon issue seems to have resolved itself. Weird.

After I make some minor changes on the local computer, ST says it is syncing for a very long time at 97-8%, even after the remote computer shows Up to date. This is a local wireless home network with only 2 laptops – is that normal?
