jQuery on local computer - need to download all .js and .css

Is it possible to download all .js and .css files that i need.

(i'm using UI datepicker, and I did download all .js required, but when i tried to download all .css i got an headache when i found out how many @imports, and @imports inside @imports there are)

So is there a convenient way to download all .js and .css?

Thank you!
