Error code: 4　（temporary file)

I gotten to follwing message wiht WinSCP5.7.6

Error code: 4
Script: Transfer was successfully finished, but temporary transfer file 'XXX.filepart' could not be renamed to target file name 'XXX'. If the problem persists, you may try to turn off transfer resume support.

I checked https://winscp.net/eng/docs/resume#automatic and tryed to cheange it.
but, problem is not solved, same error

Preferences > Transfer > Endurance > Enable transfer resume / transfer to temporary filename > Disable

Do you have any idea solve the probrem.

If you get the problem in scripting, you better use -resumesupport=off as documented on the page you link to.
