WinSCP does not have such limit. Can you upload the file using any other WebDAV client?
I am getting 413 error while uploading greater than 100 MB file using WebDAV protocol in WinSCP. Till 100 MB files uploading successfully
Getting same error for .NET assembly also.
Is there any size limit when using WinSCP protocol? If yes how to resolve this? Can you please help to fix this issue.
