I'm a fledgling to solidworks???

Not sure if this is the right place, but I've just installed Solidworks Pcb(2020.4), I've just downloaded the Altium Libraries from github and have the files (Altium Database Library V2.DbLib and Altium Database Library V2.LibPkg).

I tried installing the .DbLib but get an error message not recognised, does this need to be converted to a recognisable extension.
