This article describes how to transfer WinSCP configuration stored in Windows registry (default for installed WinSCP). If you were using an INI file, just transfer it into the new installation.

In case the source system is not online anymore, but you have an access to its data, you need to use 3rd party tool to open your registry file. You can try MiTeC Windows Registry File Viewer. Follow these steps:
