Besides what others have written about Partition Magic the same thing can be done with other applications that run under Linux.
Free partition resizers include:
DiskDrake, from Mandrake, is a FAT partition resizer.

Then there is FIPS 2.0, also a FAT partition resizer.

MasterBoot is shareware.

Partition-Manger can resize ALL of the HD formats, including NTSF.

A freeware version, Partition-Resizer is at http://www.zeleps.com/\

BTW, not a resizer, but Paragon Ext2FS allows you to mount Linux partitions from Windows.
"Paragon Ext2FS Anywhere is designed to mount Linux partitions under Windows operating systems as normal logical drives with appropriate drive letter.
The version 2.5 works under Windows 9x/ME/NT/2000/XP and is released in two versions."

Lot's of toys to have fun with!
