Uncompress CAR/SAR files from Windows explorer

I found a neat trick to use SAPCAR on Windows environments. This gives the ability to uncompress SAR and CAR files on the fly from Windows explorer. No need to type SAPCAR.

First, double-click on any SAR or CAR files. It will ask you with which program to open this file. Click on OTHER.

Find the path to SAPCAR and Click OPEN. now, click on "OK". This will fail but it's OK for now. Do the same for the other type (SAR or CAR).

Now, we need change a few registry keys to add "-xvf" to the SAPCAR call.:

You can create a simple SAPCAR.REG file that look like this (change to your path and replace LLL with your SID):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREClassesSAR_auto_fileshellopencommand] @="E:usrsapLLLSYSexerunsapcar.exe -xvf "%1""

[HKEY_CLASSES_ROOTApplicationssapcar.exeshellopencommand] @="E:usrsapLLLSYSexerunsapcar.exe -xvf "%1""

[HKEY_LOCAL_MACHINESOFTWAREClassesApplicationssapcar.exeshellopencommand] @="E:usrsapLLLSYSexerunsapcar.exe -xvf "%1""

[HKEY_CLASSES_ROOTSAR_auto_fileshellopencommand] @="E:usrsapLLLSYSexerunsapcar.exe -xvf "%1""

Once this file is created, double-click on it.

There ya go. This will decompress SAR and CAR files in the current directory. from a command prompt.
