Convert binary to file

9 posts in this topic

I use this to convert a file in binary mode.

$File_Handle = FileOpen($File_Path, 0+16)

$File_Content = FileRead($File_Handle)

FileClose($File_Handle)

FileWrite("prova.txt", $File_Content)

How can I convert the new file (in this case, prova.txt) back to the original file?

Thanks for help

FSoft,

Just open the new file for binary writing: ;)

$File_Path = "fred4.au3"

$File_Handle = FileOpen($File_Path, 0 + 16)
$File_Content = FileRead($File_Handle)
FileClose($File_Handle)

ConsoleWrite($File_Content & @CRLF)

FileWrite("prova.txt", $File_Content)

$File_Handle = FileOpen("Original.txt", 2 + 16)
FileWrite($File_Handle, $File_Content)
FileClose($File_Handle)

But have you looked at what is in prova.txt? :)

@Melba: Thank you for your reply, but you don't understand what I'm trying to do.

I have the following script:

$File_Path = "test.zip"
$File_Handle = FileOpen($File_Path, 0+16)
$File_Content = FileRead($File_Handle)
FileClose($File_Handle)
FileWrite("prova.txt", $File_Content)
Exit

The file "prova.txt" contains the binary version of the file "test.zip".

Now I want another script to open the file "prova.txt" and convert it back to "test.zip". It's possible to do this?

Thank you for help!

Hi Phoenix. Thank you for the answer, however that script uses encbin and decbin to do the work. I don't want to rely on 3rd part components.

It's possible to do everything in pure AutoIt?

I don't really understand. You have a binary file, and write it as Hex-encoded string in a new file. Now you are looking for a way to convert this string back into a binary file?

; read binary file
$hFile = FileOpen($sBinaryFile, 16)
$bBinary = FileRead($hFile)
FileClose($hFile)

; write hex file
$hFile = FileOpen($sStringFile, 2)
FileWrite($hFile, String($sBinary))
FileClose($hFile)

; --------------------------------------

; read hex file
$hFile = FileOpen($sStringFile)
$sString = FileRead($hFile)
FileClose($hFile)

; write new binary file
$hFile = FileOpen($sNewBinaryFile, 18)
FileWrite($hFile, Binary($sString))
FileClose($hFile)

@ProgAndy: That doesn't work. I tried with a PDF and the new file created is corrupted.

There was a small typo. This works for me:
$sBinaryFile = "test.png"
$sStringFile = "testbin.txt"
$sNewBinaryFile = "test_out.png"

; read binary file
$hFile = FileOpen($sBinaryFile, 16)
$bBinary = FileRead($hFile)
FileClose($hFile)

; write hex file
$hFile = FileOpen($sStringFile, 2)
FileWrite($hFile, String($bBinary))
FileClose($hFile)

; --------------------------------------

; read hex file
$hFile = FileOpen($sStringFile)
$sString = FileRead($hFile)
FileClose($hFile)

; write new binary file
$hFile = FileOpen($sNewBinaryFile, 18)
FileWrite($hFile, Binary($sString))
FileClose($hFile)
