I want to copy files onto either Win9x or Win2K computers with a single batch file. The files will be copied into different locations depending on the OS. The batch file needs to identify which OS exists. I know the syntax is something like: IF EXIST c:\windows GOTO batch file lines or IF EXIST c:\winnt GOTO other batch file lines I am looking for the exact syntax including any ":" etc. that may be needed. Thanks

In all NT systems, the %OS% variable is set by default to "Windows_NT" (no quotes), and in other systems, such as Win9x or DOS, that variable is not set by default (though the user could set it). Using that would be something like this: if "%OS%"=="Windows_NT" goto win2K goto win9x Another possibility is the output from the VER command: ver |FIND "Windows 2000" > nul if not errorlevel=1 goto win2K ver |FIND "Windows 9" > nul if not errorlevel=1 goto win9x echo Your operating system is not supported. goto eof Those are two possible and usual methods. I leave the choice to you. -- Leonardo Pignataro - Secret_Doom -- secret_doom@hotmail.com www.batch.hpg.com.br
