| (1) Create a new file.
| (2) Copy into it the bytes I will left from the original file.
| (3) Remove the original file.
| (4) Move the new file to be the original file.

| The problem with this process is that it uses lot of disk I/O.

um, use and editor for doing things like this?  *gg*
you'll need a proper editor and lots of RAM anyway....

or try "dd". it can seek to a given block number and then copy out the
bits you want to have.
