Bypassing steam on games I already own

every game i have if especially if it has Denuvo or even something other than steam i still have to use steam to re register and verify the game before i can even do anything with it..
so i just unpack the game start downloading it with steam and pause it and close steam..
then copy the unpacked game backup into the the game directory in steam.. reopen steam and begin downloading again..
relaunch steam and it will use those files to complete the install instead of downloading..(wich is far faster than downloading) unless the game has an update then it will download too.. sometimes games with large files that have been modified by an update will be redownloaded and replace the existing..
so if there are no updates to a game it will verify and install quickly with that method without having to download the entire game..
