Hi Team,

I need to integrate winSCP SFTP in one of my application.
Please can you help me to understand the process.

Is there any policy where I need to purchase this or this is available free on web.

Please suggest!

Sorry, but that's too vague. How integrate?
You may want to use WinSCP .NET assembly:

Hi Team,

I am trying to upload 18 files of 233 KB each from one windows server to another Unix server.
It is only allowing to send only 15-16 files and giving below error message:
The remote server returned an error: (409) Conflict.

Hi,

Please can you help me to understand if there is any restriction with winSCp that it will upload only files of some fixed size. When I am trying to upload 18 files of around 233mb size from one server to another..it is only uploading 15 or 16 files.

Please can you help me to understand, if there is any restriction with file size while uploading using winSCP SFTP.

There are no restrictions. It makes no sense whatsoever that client would restrict you anyhow.
If you need any more assistance, we need a session log file.

Hi Martin,

Please can we connect on call or on screen sharing session to discuss on this issue.
I will share my screen and will show you the issue.

Hi Martin,

I am trying to upload 18 files of 256 mb each from one windows server to another windows server.
However, it is only uploading 15-16 files. So was wanted to check if there is any restriction with the file size while uploading using winscp.

I already wrote above, that there are no restrictions on WinSCP side.

And you didn't provide any more information.

At least post a log file (Session.SessionLogPath).

Hi Martin,

I am geeting below error.

Timeout waiting for WinSCP to respond - WinSCP has not responded in time. There was no output. Response log file C:\Users\User\AppData\Local\Temp\wscp0644.038CA86C.tmp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

Please can you help me asap on this

Hey martin,
Please can you help me asap with the above error.

WinSCP was working for you before. What has changed since?

Until you provide us with more details, I can only point you to the documentation:
https://winscp.net/eng/docs/message_library_timeout_waiting_to_respond

HI Martin,

I have changes the logs path to D:\WINSCPLog.
Still I am getting below error with winscp: 2/10/2020 12:25:30 AM, SendToSFTP,Access to the path 'D:\WINSCPLog' is denied.

Please can you help me on priority to get this fixed.

Regarding the documentation link you have provided, from That I have already implemented all solutions but no luck. Winscp is already updated, I have changes log path as well.

Please provide the resolution asap.

So use a path, where you have a write access too. For a test did you try some temporary folder or a folder where everyone has a write access?

Regarding the documentation link you have provided, from That I have already implemented all solutions but no luck.

What specifically did you do?

Hi,

Winscp is never working for me on my windows server. I have provided all required write permissions to this folder.
Regarding the document for fix, I have updated the winscp, changes log path..tried all mentioned steps, still no luck.

Please can you help us.

Thanks!

In what environment do you use WinSCP .NET assembly?

Did you try setting the Session.ExecutableProcessUserName/Session.ExecutableProcessPassword?

Yes, I have tried this as well but getting error as below.
Error: The trust relationship between the primary domain and the trusted domain failed.

Please can you help us on priority to get this sorted.

Thanks!

What credentials did you use? Did you use the credentials of the local account that run your code?
Did you try to google that error message? There are many articles that cover it.
Do you understand that the error has nothing to do with your SFTP credentials, right? It's about permissions of your local account to spawn WinSCP process. (Because from the wording of the other post, which I'm quite sure it related to yours, it seems the you do miss that – https://winscp.net/forum/viewtopic.php?t=28862)

Hi Martin,
We are using winscp on our windows server with .Net Framework 4.5.
We tried with exe but it is working however when we are integrating this to our web application, it is giving us error.
We are using the credentials of Windows server, where we need to send the file.

Please can you help us furtehr on this.

Regards.

Sure. But is it a console application, WinForms application, WPF application, web application, a service...?

Hi Martin,

Please can you provide any solution for error: System.TimeoutException: Timeout waiting for WinSCP to respond - WinSCP has not responded in time. There was no output. Response log file D:\WINSCPTemp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

This is really impacting business as we are stuck with this issue since long.
Let me know, if you need to sync up to discuss further on this.

So did you use the credentials of the local windows account that runs your web server for the Session.ExecutableProcessUserName/Session.ExecutableProcessPassword?

Anyway, WinSCP .NET assembly is not designed for use from a web server. See:
https://winscp.net/eng/docs/library#purpose

... it is also difficult to use the assembly within a restricted environment like a web server, that limits or even restricts execution of external processes.

Having that said, most users are able to use the assembly even from a web server. I do not know what's specific about your setup.
