This comes up from time to time. I click on a file icon and receive a "No-No" message, such as: "This file needs 'My.exe' to open files of DAT type. Where is 'My.exe?' " I have no idea what the machine is talking about. Comments appreciated, with definitions, in low computer literacy language.
Thank you.

Windows is just telling you that you need a program installed that's not there to view that kind of file. OK?

.DAT is a fairly generic extension that's applied to a number of types of files. Normally, they're internal data for an application, and never intended to be opened in on their own, so they have no file association bound to them. Perhaps a file called MY.EXE was bound to the .DAT file type, and has since been deleted.

If that DAT is a big one, try opening it with the media player. Sometimes they are videos.

To STYxx-You are probably correct. The computer does not say what a "My.exe" is but it sounds like it is a program. I often do not understand why I should open a "DAT" file.
Further comments?
Thank you all.
