I'm not sure I've understood you completly. Anyway, to create files of
arbitrary size you can use the program truncate.

For example, to create a 1GB file named test with truncate:

# truncate -s1G test
# ls -l test 
-rw-r--r--  1 root  wheel  1073741824 Jul 24 23:55 test

For more information: read truncate(1) manpage. You may also want to
take a look at dd (read dd(1) manpage).
