HELP! How do I repack Driver.cab and SP2.cab

[jbarnes007]

I know this sounds stupid, but how do I repack driver.cab and SP2.cab? I can unpack them just fine using winrar or winzip but for the life of me cannot repack them as valid cabinet files. The easiest way please!

makecab is how you repack them, but you'll need to generate a listing of all the files to included.

For cabbing multiple files in a directory, I use PowerArchiver because I don't know how to do it with makecab.

What is the trick for cabbing multiple files?

[eirogge]

a ddf-file which has to contain a listong of all files and some parameters for makecab

[totoymola]

Yeah. I saw that somewhere. But I don't know what's inside the ddf file. Can you post an example?

[eirogge]

easiest way is to make a fake setup with iexpress.exe.

use some large files. while it is compressing go to the folder you are compressing, there is a temp ddf-file. dont know if it has a ddf extension or a .tmp or whatever *g*

edit: i google't around a little bit and found the following sample file on msdn:

;*** Sample Source Code MakeCAB Directive file example
;
.OPTION EXPLICIT   ; Generate errors 
.Set CabinetNameTemplate=SampleCab.cab       
.set DiskDirectoryTemplate=CDROM; All cabinets go in a single 
  directory
.Set CompressionType=MSZIP;** All files are compressed in cabinet files
.Set UniqueFiles="OFF"
.Set Cabinet=on
.Set DiskDirectory1=SAMPLECAB.CAB
manifest.xml
WebPart1.dwp
WebPartLibrary1.dll
;*** <the end>

so thats the basic structure. you have to use makecab /F sample.ddf to use it but i', not sure if this will give best compression.

nuhi probably knows about this from his nLite project.

edit2:

rem Compressing driver.cab
echo .Set Cabinet=on>> driver.ddf
echo .Set Compress=on>> driver.ddf
echo .Set CompressionType=LZX>> driver.ddf
echo .Set CompressionMemory=21>> driver.ddf
echo .Set CabinetNameTemplate=driver.cab>> driver.ddf
echo .Set MaxDiskSize=CDROM>> driver.ddf
echo .Set DiskDirectory1=i386>> driver.ddf
for /f %%i in ('dir /b i386\driver') do echo i386\driver\%%i>> driver.ddf
makecab /f driver.ddf
del driver.ddf
del setup.inf
del setup.rpt

guess where it came from? ;D http://jdeboeck.msfnhosting.com/
