Hi,
Which FTP server are you using. In my earlier project, I tried to use an FTP
server on the Linux machine and I was never able to download the last byte
of the file. The call used to just hang there. Then I tried the same code on
a different FTP server (on HP) and it worked beautifully.
So it might be a problem with the ftp server. Can you please try some other
FTP server also.
Regds,
Gokul
