    Default How do I open a dat file?

    Registered forum members do not see this ad.

    I've been sent a dat file and don't know how to open it. By the wording of the email, I should be able to open it in Autocad. Is this correct? Are there any tricks to doing it? I don't want to mess with the file incase I damage it.

    A file extension of .dat could be any format. It is a very generic name used by lots and lots of people. Can you view it with a text editor? Is it human readable? -David

    I was told I was being sent a drawing, so yes, I presume it began life as a .dwg file.

    Default dat file

    is commonly used by an operating system

    Eg Mac users often have trouble sending files to people who need to view on a PC

    Either that or the file got corrupted by the sender

    Cheers

    what are the first few characters of the file if viewed as text? If it is an AutoCAD file it will start with (something like) AC1015

    If it does then it has probably just been renamed so renaming back to *.dwg should open it. If it doesn't start with ACsomething it's not a .dwg file
