Understanding WINSCP log file

Hi, we download about 20 files everyday from client SFTP server using WINSCP automated script. The client is asking us to confirm that all the files have been transfered completely in terms of data packet sizes. Can we achive this by looking at the lines below from the log file?
Type: SSH_FXP_OPEN, Size: 56, Number: 4867
Type: SSH_FXP_HANDLE, Size: 10, Number: 4867


our log for one file lookslike this:
. 2011-01-03 14:41:08.126 Copying "/OCFSFiles/csos-qa/SEVLDSS_20110103.txt" to local directory started.
. 2011-01-03 14:41:08.126 Binary transfer mode selected.
. 2011-01-03 14:41:08.126 Checking existence of partially transfered file.
. 2011-01-03 14:41:08.127 Opening remote file.

Do you want to check that all bytes of the file were transferred? You cannot do this just based on packet sizes. If you increase the log level, to have packet contents logged, you will have enough information for the calculation. But wouldn't it be easier to check the local file size instead?
