It is recommended to execute ''[[executables|winscp.com]]'' from an existing console window (such as from Windows Command Prompt – ''cmd.exe'' or PowerShell). \\ &screenshotpict(scripting_debugging) \\ The ''winscp.com'' inherits the console((A ''winscp.exe'' always creates a new console that closes when WinSCP finishes.)) and when it exits with an error, the error is preserved on the console, allowing you to inspect it. | ||
