erm...ok. But i want the free version

What do you mean there all normal? It has the extension of rsrc and it wont open on a MAC so hows that normal??
Also the "dreamweaver installer" has no extension at all!
The only
legal free version is the 30 day trail version that you can download from the Macromedia web site. There are no others.
The file with the .rsrc extension is in essence a compressed data file used by the Dreamweaver installer application which can open the file, expand the encapsulated files and install them in the proper location on your computer. This is
normal because it is part and parcel of the Dreamweaver install and has no meaning or value in any other context.
The Dreamweaver installer does not have an extension because it has associated Type and Creator codes that identify it to the Mac OS as an executable program. The Type and Creator codes are far more powerful and flexible than the crude three character extensions used in Windows and Unix.
Before you ask the .DS_store file is normally invisible on the Mac and if this were in a .dmg file would control how the OS X Finder displays the contents of the image. Every time you change something in Finder's View menu a .DS_Store file is created, or modified, in the currently selected folder.
