Cannot overwrite remote file - while doing $session.PutFiles

Hi,

I am getting "Output: [Cannot overwrite remote file " message while writing files to sftp server using "$session.PutFiles"
I am uploading the files using WinSCP .NET assembly.
I noticed that file upload is failing when I create a directory using "$session.CreateDirectory($remotePath)" and then load data to this directory using "$session.PutFiles".
Directory path is getting created, but files are not getting uploaded.

If I try uploading files to other directory path which already exists, then it is uploading. Only for new directory created, files are not uploading.


Error message in log file:
Output: [winscp> put -delete -nopermissions -preservetime -transfer="binary" -- "<Source local file path>" "<destination vm file path>"]

Output: [Cannot overwrite remote file '<destination vm file path>'.]
ExeSessionProcess.ProcessEvent entering
Scheduling output: [General failure (server should provide error description).]
Scheduling output: [Error code: 4]
Scheduling output: [Error message from server: Failure]
Scheduling output: [Common reasons for the Error code 4 are:]
Scheduling output: [- Renaming a file to a name of already existing file.]
Scheduling output: [- Creating a directory that already exists.]
Scheduling output: [- Moving a remote file to a different filesystem (HDD).]
Scheduling output: [- Uploading a file to a full filesystem (HDD).]
Scheduling output: [- Exceeding a user disk quota.]

Please post some code. Also attach a full session log file showing the problem (using the latest version of WinSCP). Do not remove the paths from the log. Or at least replace them meaningfully with some example paths.
