Can not remove temporary folder

I open the file on the server, nothing in it do not change, just close. And I get the error "Can not remove temporary folder ..." Why do I see this error and how to fix it?

How do you "open the file"?

I open a file using the built-in editor by double-clicking

Thanks for your report.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
