Is it possible from this log to find the file size of myFile.csv that was transferred?
I might guess that this is what the Transferred field in the line Copying finished: Transferred: 61,938, Elapsed: 0:00:00, CPS: 267,853/s contains - is that right? if so, what are the units?
I have been unable to find online any documentation on what all these lines of log actually mean - some of them are plain English enough to be understood, but many contain terms and references that I do not understand. All searches for specific codes have been successful (special code 12 closes the connection for instance), but I cannot find any help determining the file size of the file that was successfully transferred - all such queries lead to questions about the log file size, not the transferred file.
Any help greatly appreciated. If you know of any documentation on reading the logs, a link would also be really helpful!
EDIT: To be clear, I need to interpret the logs that have been produced in the past; this is not a question about in future using the logs to return the file size. I would like to know the file size that was transferred on some specific dates.
In future, I would try to avoid trying to interpret WinSCP session log files.
Use XML logging instead.
Or use WinSCP .NET assembly instead of plain scripting.
However, if you are stuck with the log, you can see the file size in the following line:
. 2020-03-07 10:01:33.667 Transfer done: 'myFile.csv' => '[Redacted]' [61938]
in this case, the file size is 61938.
