7zip multiple volumes

[panprzestworzy]

Hello

I try to divide my archive in small (500k) pieces. Already I have:

#include <7zip.au3>

#include

#include



$hWnd = 0

$sArcName = "archive_file.7z"

$sFileName = "file_to_pack.7z"

$sHide = 0

$sCompress = 5

$sRecurse = 1

$sIncludeFile = 0

$sExcludeFile = 0

$sPassword = 0

$sSFX = 0

$sVolume = 0

$sWorkDir = 0



$retResult = _7ZipAdd($hWnd, $sArcName, $sFileName, $sHide, $sCompress, $sRecurse, $sIncludeFile, $sExcludeFile, $sPassword, $sSFX, $sVolume, $sWorkDir)

above script packs my file in one big "archive_file.7z" but when i try to set "$sVolume = 512k" scripts starts and ends with a second.

What form $sVolume should have?

I have looked at the 7zip.au3 file - October 18 2012 and I do not see an option for packet size. What au3 are you using?

I couldn't find attach option so:

I'm using this part of 7zip.au3 file:

; Name...........: _7ZipAdd

; Description ...: Adds files to archive

; Syntax.........: _7ZipAdd($hWnd, $sArcName, $sFileName[, $sHide = 0[, $sCompress = 5[, $sRecurse = 1[, $sIncludeFile = 0[, _

; $sExcludeFile = 0[, $sPassword = 0[, $sSFX = 0[, $sVolume = 0[, $sWorkDir = 0]]]]]]]]])

; Parameters ....: $hWnd - Handle to parent or owner window

; $sArcName - Archive file name

; $sFileName - File names to archive up

; $sHide - Use this switch if you want the CallBack function to be called

; $sCompress - Compress level 0-9

; $sRecurse - Recursion method: 0 - Disable recursion

; 1 - Enable recursion

; 2 - Enable recursion only for wildcard names

; $sIncludeFile - Include filenames, specifies filenames and wildcards or list file that specify processed files

; $sExcludeFile - Exclude filenames, specifies what filenames or (and) wildcards must be excluded from operation

; $sPassword - Specifies password

; $sSFX - Creates self extracting archive

[b]; $sVolume - Specifies volumes sizes[/b]

; $sWorkDir - Sets working directory for temporary base archive

; Return values .: Success - Returns the string with results

; Failure - Returns 0 and and sets the @error flag to 1

Rather than using the au3 file you could just download a version of 7 zip and use things like pixelgetcolor and 'do until' strings to complete the end result you were looking for.
