   echo %VBOXMANAGE% does not exist ... exiting)
   IF EXIST input.vdi   ( %VBOXMANAGE% closemedium disk input.vdi --delete)
   IF EXIST output.vdi ( %VBOXMANAGE% closemedium disk output.vdi --delete) 
   IF EXIST output.img (%VBOXMANAGE% closemedium disk output.img)
   REM  use without .img
   set /p INPUT_NAME="Enter input file name without .img: "; 
   set OUTPUT_NAME=%INPUT_NAME%_resized 
   set /p OUTPUT_SIZE="Enter Size (MB) (e.g. 15000): "
