The simplest way would be to just use FileToStr() and have the whole file in a string. FileToStr() can open files which are open by another app (which fOpen() won't do), and closes them immediately, so there's no colision.

You can then proceed by doing your operation on the string received (chopping it in any manner you like), or by copying into your private copy of the file, by StrtoFile() and then opening that copy with fOpen() and erasing it when you're done.
