You can use time patterns to make the log file name unique.
See https://winscp.net/eng/docs/ui_pref_logging

Since I've scheduled my script to run every 2 hours, I just need that every two hours, thi same script generates a filename.log but not writing the logs on the same filename.log but generating a filename1.log and in the next two hours e.g filename2.log, can Winscp achieve that by adding something else to these lines

"/log=C:\logsdelScript.log" /loglevel=1" ^



Thanks
