Archiving and compression of files in Windows before extracting #

Instructions #

  1. Download 7za.exe from 7zip
    • Download the standable version. Usually contains the description: "7-Zip Extra: standalone console version, 7z DLL, Plugin for Far Manager"
  2. Run on target machine (Windows)
    1
    echo PASSWORD_FOR_ZIP_FILE| 7za.exe a -mhe -p zip_file_name C:\target\folder\*
    
    • Note: Make sure PASSWORD_FOR_ZIP_FILE is next to the “|” pipe symbol, no space in between. If it has space in between, you have to include the space in the password
