Boom Library, Mattia Celotto, Rock the Speakerbox, Articulated Sounds, and plenty of other industry standard libraries are delivered like this.
You could use any industry standard sound library managers like, Soundly - free, SoundQ - free, Soundminer or Basehead - some of these even come with a free sound library - to easily select, drag and drop the part of the sausage files you want into your project. These files are also embedded with tons of useful metadata, which makes it even easier to scour for them in your database by searching keywords.
Even then, these aren't exactly supposed to be dragged and dropped into a project, obviously you could use them that way if you wanted, but this was made for people who would want to further develop their own sounds using these and other sound libraries' assets as building blocks.
Hope this helps you.
