Bug in Internet Explorer's FTP mechanism?

[StandaK]

Hi all,
I'm developing FTP Server and I'm standing in front of quite interesting problem with handling FTP URLs in Internet Explorer: consider this FTP URL:
ftp://127.0.0.1/=Temp=/Update/hi/2/Main.upd
The physical path of FTP's root is c:\=FTP=Of course Main.upd is file. But, when I click on this URL in Internet Explorer, I can see that it sends CWD command instead of RETR to my server! Here's the log from server:

> USER anonymous
< 331 Password required for anonymous
> PASS IEUser@
< 230 User anonymous is logged in
> TYPE I
< 200 Type set to: I
> PASV
< 227 Opening passive mode (10,28,14,98,10,190)
> CWD /=Temp=/Hi/update/2/Main.upd
< 501 CWD failed /C:/=FTP=/=Temp=/Hi/update/2/Main.upd/"

> USER anonymous
< 331 Password required for anonymous
> PASS IEUser@
< 230 User anonymous is logged in
> TYPE I
< 200 Type set to: I
> PASV
< 227 Opening passive mode (10,28,14,98,10,190)
> CWD /=Temp=/Hi/update/2/Main.upd
< 501 CWD failed /C:/=FTP=/=Temp=/Hi/update/2/Main.upd/"

I tested in on Windows 2000...I really don't why IE tries to treat the FTP URL as a path and not as a file.

Well, IE doesn't know that. I'd assume its trying to browse the place given by the url. Isn't the CWD followed by a RETR later in the progress?

Your server's response:
[ignore]
< 501 CWD failed /C:/=FTP=/=Temp=/Hi/update/2/Main.upd/
[/ignore]

You sure you want to expose the local file structure to the client rather than a virtual one? IMHO the FTP client shouldn't know anything about C:

That's just the problem - CWD is not followed by RETR...IE sends CWD twice instead..

Yes, that's physical directory structure.

Don't know whether yes or no, but I think in this particular case it is not the problem...

Now I found this out: When I try the same thing on WinXP, everything is OK, IE sends just RETR..
