    I am having trouble opening a "dat" file. I have read much information about the Set Association, etc. and am still confused. Can you help me please? The person who sent it to me said I should use a Adobe Reader, but this is not like this. I know about pdf. files and can open them, etc. but not this dat.file

    .dat files indicate a file that has arbitrary data. That means it's not associated with any one particular program or application. When you see a file with a .xls extension, you know it's referring to an Excel file, and so on. But with .dat files, you have to figure out how to open it yourself and it may not be the same program each time. The first program I'd try opening it with is notepad but since the person who sent it said to use adobe reader, try opening it with adobe reader!
