my computer moves download content to my arcives

as it says above every time I download unity content like the unity island or even some textures it sends it to my archives and I cant get them into unity! pleas help me out if you can.

For a whole project like unity island, cut and paste the entire folder (That's the project folder) into My Documents / Unity Projects /, or anywhere else you want, then in unity - go to file->open project-> Select the project folder that you just downloaded. After that, file->open scene-> Select the appropriate scene.

For individual objects or textures, cut and paste them into your PROJECT assets folder, then in unity under the 'project' tab, you should see the object there in a folder or just a file. Drag and drop into your scene / hierarchy to import it into the scene.
