Question : Quickly add permissions to large number of files?

I am currently using icacls.exe to apply permissions to a large data directory. I need to give a specific gorup access to anything and everything within this directory.

icacls.exe U:\*.* /grant us02p01\AD_GROUP_NAME:(OI)(CI)F /C /T

icacls is working fine I was just curious if there is a faster way to apply permissions like this or a better way to run the command.
