If you want to chop the END of a file off, the ever-so-cleverly-named ftruncate will do that. http://php.net/ftruncate If you want to chop the FRONT of a file off, I don't think you can do that... In fact, given the way some operating systems maintain their file catalogs, I'm almost positive you can't do that. What about reading the rest of the file and store it in a new file?

Then delete old file, and rename new file to old file and you have what you need i think. Tijnema
