WinSCP doesn't transfer file fully but shows 100% completed

HI All,
We are using WinSCP 3.7.6 in conjunction with Informatica in an automated manner to SFTP flat files from Informatica server to Sybase IQ server. Sometimes (only sometimes) a particular file (apparently mostly >10GB) when the file is transferred, the transfer dialogue box shows 100% complete. Also the file transferred doesn't show the .filepart, but still when we check the file SIZE of the file transferred is LESS than the size of the file generated on Informatica server. We are not able to understand the reason for Partial file transfer

Please first upgrade to the latest stable version. If you experience the problem again, let me know.

I'm experiencing the same problem with version 5.7.5.0 . Can you please help me?

@RahulMohan5984: That's not the latest version. Did you try the latest one?

I just had the same experience, v5.17.10 (latest version as of this morning).
Notably I copied large >5gb VM image files and ami install scripts from a remote source to a cifs file share by dragging it over to my File Explorer window.

@mikeS: What exactly happens at the end? Does WinSCP hang? Or timeout?

Please attach a full session log file showing the problem (using the latest version of WinSCP).
