What is the best way to give all users of windows XP access to create/write to files in c: drive. I do not want those permissions to be inherited to all other folders on the same drive. This access is a requirement to get a business critical app to function.
That will grant everyone the Modify right to the top of C:\ and cause it to inherit. To enable inheritance, use this version:
The OI and CI rights are what govern inheritance.
If you're on Windows 7, it's similar. NOTE: the C - Change switch is now M - Modify in icacls.
icacls replaced cacls as of WinVista.
