Insufficient space in folder xxx , but acually I have

My G driver have 46.5G free space, but syncthing complain Insufficient space in folder

Then I find this settings and change to minimum 1GB

But still got this error , why and what should I do to solve it ?

And I found syncthing would quit (without notification) after some times.

Check the corresponding setting for the folder under folder settings.

Yeah, I found it. Though I think the error message should point out how to walk through this situation, it cost my two hours to figure out…
