DLLs in the GAC

Today I have installed Faceted Search 2.5 (a CodePlex tool). The dll files were not copied to the GAC (c:\windows\assembly) with the batch file which is provided together with the Enterprise Library Package. So I had to copy the files manually to the GAC. First I tried to copy the dll files from one directory to the other in the same explorer window. A collegue of mine told me that it is only possible by opening another explorer window, selecting all files and dragging them to the assembly directory in the other window. See picture below
