why is ftp_get not working?

[John]

Are there any precautions that I should take when downloading a file
from a remote file on Linux platform to a local file in Win98
platform? I am using the method ftp_get
$remotefile = '../products.txt';
$localfile = 'C:/data/products.txt';
ftp_get($conn, $localfile, $remotefile, FTP_ASCII))

Thank you
John
