Filepart extension error while transfering with SFTP connection

Hello,

I'm facing an issue while I try to transfer .docx or .pdf file from an SFTP connection.
At each time I got a Permission Denied because of a .filepart extension as you can see on the picture.
I have tried to do the same things with an FTP connection and it works.

Can you explain me why it doesn't work with an SFTP connection?

Thanks

Try disabling transfer resume:

I have tried this without success.

Only an FTP connection is working.

Thanks for your reply.

Please post a session log file showing that.

You will find the log session in the attachment.

You didn't disable the resume support:
