change the security permission of some files and directories to “Everyone - Full Control”.

I need to change the security permission of some files and directories to “Everyone - Full Control”.
I have the cacls command (“cacls c:\mydir\*.* /e /g everyone:f”) but the problem is that on some OS the Everyone group has a different name (like "Jeder" in German OS).
I need a command that can make this change without using the “everyone” word.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The "Everyone" group is a "well known group" with the SID S-1-1-0. You can use this information to extract the localized name.
Get SIDtoName.exe from Joeware.net:
http://www.joeware.net/win32/index.html
Then use a script like the following to set your permission; it's currently in test mode, it will only display the "cacls" command.

====8<----[Everyone.cmd]----
@echo off
setlocal
:: *** Retrieve the localized name of the "Everyone" group using sidtoname.exe:
for /f "tokens=2 delims=\" %%a in ('sidtoname.exe S-1-1-0 2^>NUL ^| find "[WellKnownGroup]"') do set Everyone=%%a
echo The local name of the Everyone group is %Everyone%.

:: *** Test mode: Remove the "ECHO" in fron of the next line to "arm" the script
ECHO cacls c:\mydir\*.* /e /g %Everyone%:f
====8<----[Everyone.cmd]----
