Thanks again, i did the change, i follow this steps :
http://www.linuxtopia.org/online_books/centos5/centos5_administration_guide/
centos5_s1-swap-adding.html#s2-swap-creating-file
But I setup bs=1M count=1024 this I learn it from:
https://help.ubuntu.com/community/SwapFaq#head-75ffcb00cefe143fc380f84d7ea92
03f16a596d0
I like it more to do it that way.
Later I reboot my PC and run the command free, it seems that now I am using
my newly created swap file, what a nice start. My linux experience is
starting to like it more, thanks to all for your help, thoughts and time!

Yes and with today's kernels it provides the same level of performance.
# dd if=/dev/zero of=/.swapfile bs=1M count=512
# mkswap /.swapfile
fstab:
/.swapfile swap swap defaults 0 0
Or if you use lvm, turn swapoff the lv, lvresize the lv, mkswap the lv
again, then swapon the lv and you have a larger swap, but the swapfile
will at least be contiguous.
