I normally use lftp or filezila in my linux system to download files from the securities and exchange commission ftp website (ftp.sec.gov).

A few days ago I began trying to do the same thing using an ftp client on windows. However, I have had problems doing so. It seems that the native client that comes with windows cannot get access to data and refuses the connection (although it allows me to connect to the server). This may have to do with lack of passive mode...but I am not sure. Then I found this application and everything was going well navigating the sec ftp site until I decided to download a file. Winscp believes these files are symlinks and thus nothing happens when I try to download. I use ncftp and I had no problem downloading a single file. What is nice about Winscp is that if I solve this issue I can script a batch process to download many files. Something that seems to be a limitation in all windows ftp clients that I have looked at.

The problem is replicable by running the following lines (no password). You can also connect using the GUI, however consider that the folder data is not browsable so you have to leapfrog onto the 1062195 folder to get the listing:
open ftp://anonymous@ftp.sec.gov
get /edgar/data/1062195/0001104659-06-016816.txt

winscp believes that the file 0001104659-06-016816.txt is the symlink.

I have been all day on this. If someone could help me, I would appreciate the assistance very much.

Please attach a full log file showing the problem.

To generate 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 may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

It looks like the files are indeed presented as symlinks by your server. Please post Debug 1-level log files to make sure.

In reviewing the log detail you asked for, I can see that indeed these seem to be links. If that is the case, what is the work around? How is it possible that only winscp can see the files for what they are? all other ftp software I have tried views them as files and allow me to download the actual file at the end of the link.

Thank you!

I tried to download your file using wsftp client - latest version - and it also will not download the file using the path to the server symlink. Log posted below.

Appears that your server is returning "550 /edgar/data/1062195/0001104659-06-016816.txt: No such file or directory"

Your file does download when using filezilla as a client.

The sequence for successful down load is :-

1. Change server to the correct working directory
CWD /edgar/data/1062195

2. Then request the working directory back from the server using
PWD
The actual working directory returned using this command may be different because of a symlink in the directory tree, hence the client needs to changes to this directory if it is different.

3. Then retrieve the file using the standard list of FTP commands - TYPE A PASV RETR etc.


A previous log posted seems to infer that WinSCP does send the PWD command, hence unsure why WinSCP has issues downloading the file, the log files seem reasonably similar but slightly different where the file should be downloaded. Perhaps the Filezilla log below may help with this issue.

@mshifu: I'm sending you dev version of WinSCP for testing.

The problem was mitigated by fixing this bug:
