trying to figure out a way I can limit the size of the log file on a windows xp machine running WinSCP through command line

command line looks similar to this
"C:\Program Files\WinSCP3\WinSCP.exe" /log=logfile.txt /command "open user:pass@server.com" "get *.* c:\folder\" "exit"

thanks for your help

What that would be good for?

it would be good because the log file is 6MB after one transfer, I am doing one transfer per day, and I would like to limit the size it can grow to.
I don't want to go in every week/month and delete the file.

So you want WinSCP to delete beginning of the log in case a total size exceed certain limit?

not delete but limit the size it can grow to, so as it appends to the file it would remove older entries needed to keep the file size at or below the predetermined setting.

That's what I've meant

Added to TODO list.

thank you

Hi there,
Do you have solution for the above?
How to control log verbosity from command line? I don't want to use ini file with other 1000 options.
When I am using ini and have just logging section saved to it, it works fine but after script is run, it write all other options to ini file. That is the reason I dont want to use ini.

You can set the INI file read-only.

tracker issue contain no news, seems like this was never implemented.

don't know what you're talking about INI files.

couldn't find anything on docs (either on https://winscp.net/eng/docs/ui_pref_logging or https://winscp.net/eng/docs/logging for instance) on how to limit the file size.

and I doubt this can be properly done outside the app itself. can it? any pointers any one?

Anyprogress on this?

I confirm it would be very useful

I can agree with this as well, or some option to rotate the logging.

Hi Guys,
Was there ever a solution to this? I would really like to purge/limit the log file on a nightly basis but can't see how.

There was no improvement in this respect yet.

+1 I could really use this feature.

I'm raising priority of this request.

Very wait this feature! Thanks!

I second the need for limiting log size option

Can you describe your use case? How big does your log file (for a single session) get that you need to limit its size?

I agree that this would be a nice feature.

Use Case:
Synchronizing directories on a production web server and offsite backup server nightly

After a single session, log file reach's 45MB

Is it not possible to use the following syntax?
WinSCP /log=logfile.txt /logsize=5MB /command "open user:pass@server.com" "get *.* c:\folder\" "exit"

If the filesize reaches 5MB, a new log-file (with datetime-suffix) will be created.

This way, we can use a daily transfer-script to transfer the old log-files to an archive.

+1 for higher priority

Hi all,

I also need help to this.

My "logs" folder must not exceed 100mb. But I can't limit each log size file in it.

How can I do this, please ? I 'm little newbie on this work.

It will be possible to limit log size on WinSCP 5.10:
