Re: I have the same problem - Here is my Log file

I'm sorry, but WinSCP cannot work with a server that does not allow the CWD command.

I have the same problem - Here is my Log file

Looks like I have the exact same problem both using automation and the UI.

The error says the server rejected command "CWD". I'm unfamiliar with this command.

Here is the log file contents. I have masked my FTP server and user, for obvious reasons but we can see the error as it occurred

Re: Empty file downloaded

Thanks for your reply. I don't think the other user had turned this logging on, or is that not possible? Anyway I'll try to recreate the issue myself.

Re: Empty file downloaded

We need a session log file (/log) to investigate.

Empty file downloaded

Hi there, I'm having an issue with downloading text files from an ftp server. Multiple times a day I upload files to a certain folder called outbound. From this folder a different user runs a script (see below) that downloads all these files with 30 min. intervals. After it has downloaded all files, it moves the files to a folder outbound/archive on the ftp. The script runs on Windows 2008 Server with WinSCP version 5.7.2 build 5316.

Command line: 
"PathToWinSCP\winscp.exe" /script=PathToScript\Script.txt /xmllog=PathToLog\LogFTP.xml

Script: 
option batch abort
option confirm off
open ftp://<ftpurl> 
cd /outbound
option transfer binary
get foo*.txt e:\downloads\
mv foo*.txt /outbound/archive/
close
exit

This all seemed to work great, except for the last two weeks in which we encountered twice the issue that a file was downloaded as a 0 bytes file. However, looking back at these files in the outbound/archive folder they did contain data.

So now the question remains how this is possible. At first I thought that maybe the script tried to download the file while it was still being written. However, another file that was uploaded after the 'empty' file, was downloaded correctly. So that scenario does not seem very likely.

I've attached the only logs that I could retrieve, not sure whether there should be more extensive ones.

Does anybody else have an idea for a possible reason? Should I try a more extensive script to only download the file when it is not empty and also only move the file in that case?

I hope you can help!
