Presets & Overlays help

Hi 

I am still learning both lightroom and photoshop and would like your help.  I have downloaded some presets in lightroom and overlays in photoshop.  They are now stored in the correct setting for both lightroom and photoshop.  So my question I need help with is can I now remove the files from were i put them on my drive before i loaded them to the relivent program.  Hope this makes sense and thank you in advance for your help.
