Logs are uploaded, thank you :)

Already mailed but no answer.
Crash reproduced with debug version but cannot see something wrong in trace but hope you will :)
Logs are 114GB and 2,5Gb archived. It's too much for email (sending 172 15mb pieces) and in debug information written about ftp possibility. Can we go this way?

>You can remove anything you do not want to share.
answer found :)

and more... is it ok if I'll change files name already inside the trace? I don't want to post this data somewhere

Thank you for very fast reply!
For 5 minutes I have about 3Gb of logs already and with 2,5 hours it'll be 90Gb. Do you need them all or only latest one? Sure it'll be packed but still too big I think :)

I'll try to reduce some space but I think it's not possible because if I synchro only some subfolder then there is no crash.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

As I understand from previous answers some debug version needed :)
