Thank you for confirmation. Unfortunately, it happens so rarely and I don't want to enable logging as it will produce a lot of logs until the issue occurs again.

You definitely can do that.
If you want to me investigate the zero upload, please post session log file. Name one file that uploaded correctly and one that did not.

Thank you for the reply. I don't think this is the case because other files were uploaded successfully after. One other detail is that they have almost 6,200 files in that folder. I am not sure if that has anything to do with anything.
After the upload is done, should I use
My code is very similar to this: https://winscp.net/eng/docs/library#csharp, I call
Thank you again

EnumerateRemoteFiles to get back the uploaded file RemoteFileInfo and check its Length if I want to retry the upload operation in case the remote file has 0KB?

PutFiles & Check. I don't know what Check does exactly.

Re: Files are uploaded with 0kb
With SFTP protocol, when the upload seemingly succeeds without any error, but the uploaded file is empty, the most common issue is that the target file system is full.
Common OpenSSH SFTP server on Linux system fails to report any error in this case.

Files are uploaded with 0kb
Hello,
We use the .NET assembly to upload files to a remote SFTP server via a custom C# app. The component has the version 1.16.0.16364 and it uses WinSCP 6.5.3. Recently, we had a case where a file was uploaded with 0KB. The component didn't report any errors in the app, so as far as our app was concerned the transfer was successful. Other files and lots of them were transferred properly.
Is there a way for our app to double-check the size of the uploaded file to make sure it was not 0kb and re-try the transfer if that's the case? The files are small, in this particular case the file had 1,722 bytes.
I also searched the forum and there have been other posts in the past about this very issue.
Here are 2 I found:
It seems to me that the server software was the culprit in these cases. We are going to explore that side as well but it belongs to third-party and I don't know exactly what they use and how responsive they are.
Could you please let me know if there is anything I can do in the app to detect a 0kb file upload and to re-try the transfer in this scenario? I want to make sure the transfers are foolproof.
Thank you so much!

Here are 2 I found:
- Some files are being uploaded as 0 bytes when in fact they have content
- Files are getting uploaded with 0 KB size.
