After getting this error ALL the time I thought it would be easy to search for a solution.
Now 6 hours, and not a single solution my Winscp with hundreds of sites seems totally messed up. My configurations seems totally wrong and i STILL get the same error.
I don't want errors, I simply want to upload thousands of files simultaneously
I tested the same dir on another ftp client: not a single problem. So it must be some configurationthing.
Hope for a solution.
