If the file with all the files on your desktop contains the resource pack, all you need to do is go into .minecraft and put it in the 'resourcepacks' folder. (To get to .minecraft you need to type %appdata% in your search bar, then go into .minecraft.)
If it is the map, do the same, but go into the 'saves' folder.
If the above doesn't work, then go into the resource pack, and open the pack.mcmeta (with a text editor of somesort) then see the pack format. If it is pack format 1-3, then it wont work with 1.14.4. It needs to be format 4
