    A DLL (Dynamic-Link Library) is not really made to be opened. It is a piece of executable computer code used by other pieces of executable computer code. A DLL file is usually created and compiled using a much higher level computer programming language.

    You could use a Hex viewer or editor to see a human-readable hexadecimal version of the binary data in the DLL file. There may also be programs available that will attempt to reverse engineer the binary data into rudimentary assembly language code.

    EDIT:
    Example of a basic Hex Viewer for Windows:

    Thanks very much for your kind help his response was" it all sounds very complicated"

    Would a DLL file come along with other files that are missing to make one program?

    The big question is why is your BIL messing with DLL files? The fact he doesn't know how to view the hex/machine code means he shouldn't be messing with them at all. In all my years of doing IT work, I've never had any instance where I had to peer inside of a DLL file. The only people I can think of who would need to and have the expertise to do so are software developers. And software developers wouldn't be asking relatives or forum boards on how to do this.

    Are you sure it is a .dll extension? Since it's house plans, it was most likely generated via a CAD program and likely a program like AutoCAD. If that's the case, it should have a .dwg or .dxf or similar extension. It's sort of ridiculous for the architect or builder to send files to a lay person in this format. The plans should have been sent as a PDF or similar file.

    Are you sure the file on the disc isn't trying to open a program on his computer and that program is what is missing the DLL file? Post a screenshot of what you/he is seeing.

    Hi thanks once again for your help my brother-in-law said when he put the disc in the computer the computer was telling him it was a DLL file.

    He will just get the plans in PDF format
