What do you mean, "file system" and "partition"?
If you mean you want to steal room from a DOS file system to give
to BSD, you will need to:
1) Backup the BSD data that you want to save (configuration
files you have modified, etc., basically anything that
didn't go on as part of the initial install process).
2) Run fips to shrink the DOS partition.
3) Delete the BSD partition
4) Reinstall BSD.
5) Restore your local information from your backups.
If you mean you want to steal room from one BSD filesystem for
another, and one of them is the root partition, you will need to:

2) Delete the BSD partition.

If you mean you want to steal room from one BSD filesystem for
another, and neither of them is the root partition, you will need
to:
1) Backup the partitions involved.
2) Unmount them. This probably shouldn't be necessary,
since you should be doing this in single user mode.
3) Using the disklabel -e command as root, adjust *only*
the partitions you are playing around with.
4) Manually run the newfs command to "reformat" the disk
partitions. This will blow away any data on them.
5) Mount the partitions an restore the file system contents
from the backup media.
In BSD's defense, you can *not* move the boot area for any OS
for which you have a bootable partition without a lot of work
(at best) or a reinstall (at worst, and most likely). That BSD
would let you adjust partitions that aren't the boot partition
without reinstalling is pretty amazing in and of itself.
