I am using WINSCP.COM version 5.7.7 build 6257 to transfer files to an sftp site using a private key. The upload runs via a batch script called for each file it uploads (normally 3 files) which is basically as shown below where parameters are substituted.
echo open sftp://%4:%5@%3 -privatekey=%6 >grgtransfer.sftp
echo cd %7 >>grgtransfer.sftp
echo put %1\%2 >>grgtransfer.sftp
echo close >>grgtransfer.sftp
echo exit >>grgtransfer.sftp
winscp.com /log=%logfile1% /script=grgtransfer.sftp
The script logs on and uploads OK except the first file it uploads always appears blank after completion, even though a listing of the file shows a valid byte size.
I have attached a log file showing the upload (blanked secure data items) for all 3 files showing the first file as successful and valid byte size. I am not a comms expert but can anyone see what might be the cause from the log detail.
