Okay.

Linux sorts your disks and partitions differenmtly from Windows. 

Windows puts an abitrary name on each partition, like A:, C:, D:, E:, etc.

Linu and other Unix-like systems [and to a much lesser extent, Windows 
2000] actually show all your storage as a single, heirarchical tree. You 
can add disks to the tree so that if you look in a certain directory, 
you see the contents of your disk.

The directories where new disk partitions are attached are called mount 
points. Your filesystem table [/etc/fstab] is what configures this.


The botton of the tree [shown as a slash /] is called `root' [not to be 
confused with the user root]. One of your partitions is mounted as 
root. But the directory /mnt/floppy is actually on another disk. This is 
because another disk [your floppy drive, /dev/fd0] was mounted as 
/mnt/floppy. If you look in /mnt/floppy wiht a floppy disk in the drive, 
you'll see the floppy disks contents within /mnt/floppy.

In Alexanders suggestion, the /mnt/exchange directory would be another 
hard disk. If you look in the /mnt/exchange directory [or mountpoint], 
you'd see the contents of your other OS main partition.

Hope that makes sense, 

Mike
