Is it possible to mount different folders on disk to different locations? 

I have a disk with two folders, folder1 and folder2. I'd like to mount these folders separately in my home folder, that is, to the locations:

Code:
/home/<username>/folder1
/home/<username>/folder2Is that possible? If so, how?

Solution:

Suppose you had a user on a ntfs partition, say /dev/sda1 and you wanted to map each user's document folders to a folder, say Documents/Windows in each of those same user's /home directories on your (dual-booting) Linux system. Then the following commands (in bold below) would do the trick. (Lines starting with a hash mark - # - are comments)

Code:

$ # First, create a mount point for the partition
$ sudo mkdir /Vista
$ # Then add a line to /etc/fstab so the partition will be automatically mounted every time you boot your system.
$
$ # CAUTION: The two redirection symbols (vis: >>) in the
$ # following command are essential. If you use a single redirection, then
$ # your whole fstab will be replaced by the single line, and your system
$ # will be unbootable. A simple sudo cp /etc/fstab /etc/fstab.backup
$ # would be prudent before changing the contents of this critical file.
$ #
$ sudo echo UUID=342D7D7923AC4107 /Vista ntfs-3g rw,defaults 0 0 >> /etc/fstab
$ # To get the UUID, do a ls -l /dev/disk/by-uuid. Instead of UUID=
$ # you could use LABEL= (look in /dev/disk/by-label) or just
$ # use the physical address /dev/sda1. The use of the UUID or LABEL
$ # option is preferred because it lets you move your drives without breaking
$ # your system. (Look at man fstab for more information.)
$
$ # Verify that you've got the fstab entry correct.
$ sudo mount /Vista
$ # (If the mount fails, edit the fstab by hand (sudo gedit /etc/fstab) until it works.
$
$ # Verify that the data is correct and locate the Documents folder you want to map:
$ ls /Vista/

Oh, I was logged in a Peter when I ran that. If I had been logged in as someone else (e.g., root), the last makdir command would either need to be run as Peter (i.e., su Peter -c 'mkdir -p /home/Peter/Documents/Vista') or followed by a sudo chown Peter:Peter /home/Peter/Documents/Vista so Peter could use the directory.
