Remote folder 'is not file!' bug

Dear admin,

Something seems to be going wrong with fetching a file to a remote folder where the file already exists. When I delete the file from the remote path the command works fine but when the file already exists it says "is not a file!" instead of overwriting it. I have option confirm set off. The user account has full permission to the remote location (I am running this as domain admin on server) Please see this snippet.

Thanks for your help!

Regards,
Sem

Please attach a full session log file showing the problem (using the latest version of WinSCP).

Thanks I found a workaround. Please delete my post.

Would you please rather share your workaround? Or do you really want me to delete the post?

What I did was just download the files one folder above (where the files don't exist) and then move them to the subfolders at the end of the cmd batch script.

Attached the detailed log, this issue started happening all of a sudden in multiple environments.
What is the root cause of this issue?

@Nevin: Seems like a different manifestation of this issue:
Issue 2056 – File on local network share treated as folder when uploading

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

Is there any workaround to come out of this, this started happening all of a sudden from our PROD environment.

@Nevin: Please follow the instructions from the email to help us implementing the workaround eventually.
