Extracting files from windows executables (.exe) in linux

I am trying to extract firmimg.d7 from the iDRAC firmware exe file, to be used in a drac update using the drac web interface.

The first thing to do is to strip any prepended data (e.g. a SFX stub) from the archive, using a tool called zip. You can install this tool in centos by running yum install zip.

$ file iDRAC-with-Lifecycle-Controller_Firmware_JHF76_WN64_2.30.30.30_A00.EXE
iDRAC-with-Lifecycle-Controller_Firmware_JHF76_WN64_2.30.30.30_A00.EXE: PE32+ executable for MS Windows (GUI) Mono/.Net assembly

$ zip -J iDRAC-with-Lifecycle-Controller_Firmware_JHF76_WN64_2.30.30.30_A00.EXE

$ file iDRAC-with-Lifecycle-Controller_Firmware_JHF76_WN64_2.30.30.30_A00.EXE
iDRAC-with-Lifecycle-Controller_Firmware_JHF76_WN64_2.30.30.30_A00.EXE: Zip archive data, at least v1.0 to extract

Once the file has been shown as zip archive, the normal unzip program can be used to extract it

$ unzip iDRAC-with-Lifecycle-Controller_Firmware_JHF76_WN64_2.30.30.30_A00.EXE
