FileOpen Raw Mode

[Jon]

What does the FileOpen raw mode do? Why is it useful?

[WeMartiansAreFriendly]

thats a good question..

Coming from the man himself.

So is it likely to be used by anyone in normal scripting circles for anything other than going "huh" when they see it in the help file? It don't see why it's there tbh (apart from bugging me when debugging the file code )

I described it as best i could at the start of that post (heed not the later posts as it goes into a tangent).

Just reads hex , like opening a file in binary mode (instead of text mode) in C/C++ correct?

I was playing around with this question, and found that the output from this script, when using RAW mode is much longer.. How is that?

$Filename = FileOpenDialog("Try this on image files such as JPG","", "All Files (*.*)")
If @error Then Exit

;Read mode
$Filehandle = FileOpen($Filename,0)
$Read = FileRead($Filehandle,512)
FileClose($Filehandle)

$Split = StringSplit($Read,'')

Dim $Return
For $x = 1 to $Split[0]
    $Return &= Hex($Split[$x],2) & " "
Next

MsgBox(0, "Normal Read Mode", $Return)


; Raw read mode
$Filehandle = FileOpen($Filename,4)
$Read = FileRead($Filehandle,512)
FileClose($Filehandle)

$Split = StringSplit($Read,'')

Dim $Return
For $x = 1 to $Split[0]
    $Return &= Hex($Split[$x],2) & " "
Next

MsgBox(0, "RAW Mode", $Return)

As Larry posted. You cannot read the eltoro boot image unless you read it raw by it's position on the disk. Other uses would be formating or forensic.
