[newbie] file copying

[Ken]

        I'm trying to copy a file from a FAT32 partition.  It's in the 'c:\Program
Files' of my win98 drive.  When I type "cp /mnt/win98/program
files/filename.txt /tmp/newfilename.txt" I get an error saying it can't
find the file.  I think I know what the problem is, it's the directory
"program files", since it has a space in the directory name.  So how to do
refer to this directory?
