      In windows, it is not trivial. If your C: is full and you want to expand your c: how'll you do it ?
You'll have to rely on third party software like PowerQuest's partition magic or Ranish Partition Manager.
The windows filesystem FAT 16 and FAT 32 are simple  (their performance is equally bad ),so resizing is simple.

      You can do it for / if you boot from a linux boot floppy.(Backup , change partition size, create filesystem,  restore the backed up files , and then run lilo.

      For your case, you can make the new partition as usr,
mkfs.ext2 /dev/disk2/partitionno
mkdir /t
mount /dev/disk2/partitionno /t
cp  -a /usr /t
init 1
rm -rf /usr/*
umount /t
mount /dev/disk2/partitionno /usr
rmdir /t
init 3 
 
add an entry to /etc/fstab saying that this is to be mounted as /usr

/dev/disk2/partitionno    /usr     1   1
 

Now you can work, and you'll have lots of free space.
Normally when you install software , they get installed in /usr or /usr/local

     fdisk is only a partitioning utility.
     If you want to mount a partition at boot up, add the appropriate entry in /etc/fstab

     There is an HOWTO already which describes how to add a new disk/partition.

It is simple

mkdir /mnt-point

mkfs.ext2 /dev/hdX/partitionno  (X to be substituted)

mount /dev/hdX/partitionno /mnt-point
