I want to cut a small piece of a large binary file

Recommended Posts

Hi! Please, help

I want to very quickly cut a small piece of a large binary file at the end. This piece (5 KB) I need. I am using:

# Include "Binary.au3"

$ bData = FileRead ($hFile)

$ bData = _BinaryRight ($bData, 5000)

FileClose ($ hFile)

This works for a long time. How can I do differently?

TNX ;)

That will only work with the other WinAPI functions. He needs to use the native function FileSetPos before using FileRead.

Good thing you pointed that out, I've been up too damn long today.

YES! thank you very much!

#include <Constants.au3>

$hFile = FileOpen ($hFile, 16)

FileSetPos ( $hFile, -5000, 2 )

$bData = FileRead ( $hFile )

FileClose ( $hFile )

This work very fast ;) Edited by scon
