ABAP add-on PAT file to SAR file

Hello,

I have a PAT file, for example, the file name is SAP12345.PAT, how I can cover it into .SAR file, for example, I need it to be SAP12345.SAR ?

What I have done is, I have SAPCAR.exe and it works for may windows 10, I have placed in underc:\windows32

what would be the full command for my question, regardless where I put SAPCAR.exe, regardless where I put SAP12345.PAT.

Thank you,

Hu
