# How to cache a paclet permanently? [duplicate]

I have needed to use a paclet when I did not have internet and was out of luck. Is there some way to tell Mathematica to cache and never re-download a list of certain paclets?

• @J.M. Wouldn't this indeed be a duplicate of either (3549) or (78954)? Aug 5 '16 at 13:48

• @M.R. if you look at the GraphData dvs they're missing the "Preload" and "Install" commands that ChemicalData has. Rather you'll need to use DataPacletsGraphDataDumpMyGraphData[___, "Preload"] May 17 '17 at 4:50
