AARRGGHH!! - I've done it again

  dagbladet 16:00 09 Oct 2003

A mate sent me some .dat files by e-mail. once downloaded they had that windows flag on them. I went to open the first one and was asked which program I wanted to open it in. I then made two mistakes in as many seconds. A) I forgot to uncheck the "always open with this program" box. B) I hit winzip. They aren't winzip files and now the following 23 have all got that winzip clamp thing logo on them. Can I reverse this anybody ?
And what is a .dat file.

You need to tell us what OS you are using because the method of changing file associations is different. Try typing FILE ASSOCIATIONS into help in explorer and see what it says.

Hi dagbladet. Yes you can undo the file association. You just reassociate the file type with another application. A .dat file is just a data file used in various applications. click here

Sorry forgot the basics
Win 98
The files apparently contain text only, they are reports.

But what would he associate these DAT files with?
I presume he now has every DAT file on his computer associated with Winzip.

Gongoozler, how do I reassociate the file type with another application. when i click on them, winzip automatically opens.

Right click the file choose 'open with' then choose the program you want the file to be associated with.

"open with" not offered

Repeat - What Operating System are you using?

Even if we find out the OS what are .dat files supposed to be associated with. In XP they are "unknown application" but you can`t change a known file type such as .doc to unknown application. I fear this is a registry solution but am getting out of my depth.

usually you have to push SHIFT and right click on the item to get "open with"

To get "open with" - highlight file, "shift" and right click.
