If you need a copy of 'Imagex' You can get it as part of the WAIK (windows automated installation kit) which can be downloaded from Microsoft (900mb iso download): http://www.microsoft.com/downloads/details...;displaylang=en imagex.exe also comes on some Vista DVDs (Dell oem, probably retail aswell, under the sources folder) Merging SWM into WIM 1) Paste Imagex.exe into your windows\system32 directory so that it can be accessed in CMD window from any directory. 2) open a command prompt, change dir (cd) to path with the SWM files paste the following (right click + select paste / CTRL+Z shortcut doesn't work) imagex /ref install*.swm /check /export install.swm 2 install.wim "Windows Vista Home Premium" obviously replace "install*.swm" and "install.swm" with the name of your files if its different and edit the "Windows Vista Home Premium" part to suit your version 3) Hit ENTER and it should start converting and place the new file in the same directory as INSTALL.WIM Splitting WIM into SWM Simlar idea to merging, cmd line is imagex /split [.SWM file to be split] [.WIM file/path to be saved as] [filesize] eg. imagex /split asus.swm install.wim 700
