File transfer- Filepart

i'm running winscp from the command line using SFTP and I'm using version 5.1.1

when i run winscp to transfer the file, it keeps renaming the file to extension filepart.
I get the error below:
Transfer was successfully finished, but temporary transfer file 'FPRST.PAS.QTE1TXNS.filepart' could not be renamed to target file name 'FPRST.PAS.QTE1TXNS'. If the problem persists, you may try to turn off transfer resume support.
No such file or directory.
Error code: 2
Error message from server: /XC0305T/SFTP/PWI_UAT_F00080G/FPRST.PAS.QTE1TXNS.filepart does not exist
Request code: 18
(A)bort, (R)etry, (S)kip, Ski(p) all: Abort

how do I fix this??
