WinSCP creates temporary file with .filepart extension even after successfully transmitted

All the files gets uploaded successfully comes with .filepart extension when using Winscp.

After spending sometime on this, it seems WinSCP transfers the data with temporary filename first and then renames the file after successful transfer to able to resume from partial file if the transfer is interrupted. And while using stfp its doesn't allow to change the file name as part of the same operation.

You can get over this problem by disabling the resume/transfer option in WinSCP
