Re: WinSCP File transfer issues

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

Are you able to transfer the files using any other FTP client running on the same machine as WinSCP? If you are, please post its verbose log file too.

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

WinSCP File transfer issues - 11/17/2021

The file transfer or copy or download used to work fine for me. Suddenly I noticed it is not working. I did end up uninstalling the WINSCP I had and installed again Vr 5.17.7 and it is still not working. I get no error or nothing but it does not work when I copy a file from server to my local or vice versa. I try to drag and drop nothing works.

Hi Martin,
That was a nice support from you, Thank you!.
Not sure how that mask setting got changed (no clue), but your solution worked nice. I think when I tried to uninstall and install WinSCP I always tried copying back my favorites exporting the WINSCP.ini file and I think it copies this preference too :).
But thank you for your support, I was trying to see if I can call a 800- No to get the WinSCP support, but when such help works it is always great. Appreciate your help, have a nice day.

Thank you.

Re: WinSCP File transfer issues

@Rachana: I was asking for WinSCP log file. What you have posted seem to be a log of your application. The only errors I can see there are:
The process cannot access the file 'F:\FTPRoot\FileTrac\LA\Inbox\12908183.AE201.211116.7691499.CD.Rev 0.pdf' because it is being used by another process
That's a very different problem than you have reported originally. I'm lost. So what problem are we solving?

Does WinSCP is compatible with Windows 20H2 version

Hi Team,

We are in the process of upgrading our current Windows 10 PC’s to Windows 10 version 20H2.
Please advise of the following:

Required OS build compatibility matrix against WinSCP against all its versions
1) If unable to provide a link to such a matrix, please advise if testing is done on winscp on OS build 20H2
2) If testing is not done on OS build 20H2, can you advise of a time frame in which if you plan to complete testing for 20H2.
3) If you do not plan to test winscp on build 20H2, will you still provide support or any additional resources trouble shooting issues we may encounter on this build?
Have any of your existing customers migrated to build 20H2? If so, has there been any reported issues?

Could you please provide us the answers for the above query

Regards
Rachana

Re: WinSCP File transfer issues

There's nothing in the log you have posted. Not a single transfer. Not a single error message. It just shows mostly idle WinSCP GUI session with few directory changes. Please post complete log showing the problem.

Regarding your 20H2 question: WinSCP works on all recent versions of Windows:

Re: WinSCP File transfer issues

Hi Martin,

Thank for your response

I have already attached few error screenshots in the word document, more specifically I can say that when user attempt to transfer the file receives this error "Error listing directory: Could not retrieve directory listing" Is it possible to get on call to address on this issue exactly. Recently (30-11-2021) when we tried transferring file to remote directory we didn't find this error "Error Transferring the file: Copying files to remote side failed". Also attached additional session log file.

Re: WinSCP File transfer issues

So what is the point of you posting the FileZilla log? What did you want to show by that? Even in the FileZilla log I see that your FTP server randomly fails the LIST command with 550 error. So something seems to be wrong with the server.
2021-12-13 11:37:57 12548 1 Command: LIST
2021-12-13 11:37:57 12548 1 Trace: CFtpControlSocket::OnReceive()
2021-12-13 11:37:57 12548 1 Response: 500 Command not understood.

Re: WinSCP File transfer issues

Hello Martin,

As per your post dated 2021-11-15 "Are you able to transfer the files using any other FTP client running on the same machine as WinSCP? If you are, please post its verbose log file too". We tried, with FileZilla and it was able to transfer the files. We attached the logs for your review and assistance.

Requesting your help to determine what is causing the issue in WinSCP.

Thanks in advance.

Re: WinSCP File transfer issues

But you still didn't post WinSCP log file with the problem. All WinSCP logs you have posted show no activity.

Re: WinSCP File transfer issues

Hi Martin,

I have already attached WinSCP logs (2021-12-02) 09:35 for your reference. Attaching the log file again.

It would be great if we could get on call to discuss this in detail and it would be helpful to find a quick solution. It is affecting users since very long.

Regards,
Rachana

Re: WinSCP File transfer issues

And I have already wrote you that the logs you have posted show no activity. There's not a single file transfer in the log you have (re)posted. Please post a log that actually shows your problem with file transfers.

We do not provide phone support.

Re: WinSCP File transfer issues

As before, there's not a single file transfer in any of the logs you have posted. Search the logs for "Copying files to remote side failed". You won't find anything.

Can you just post a complete log of a session that includes single failed transfer?

You keep posting snippets of idle sessions.

Re: WinSCP File transfer issues

Normal logging level please, not Reduced. + Complete log of a single session please.

Can you reproduce the problem with single foreground transfer? Or does it happen only if you use many parallel background connections?
