need some help opening a .dat file.....

I don't know if will help, but I noticed in a thread someone (@chefsuccess.com) mentioned, that, you need to use the restore to import the file.

I don't use the software, so, I have no idea on the steps/procedure.

Goodluck*Smile

EDIT:

Dam* those how-to web sites have everything.

Hope this helps: How to Switch Pampered Chef Files From One Computer to Another

 

Associate .dat files to NotePad

Hi Rick

Right click a dat file, choose 'Open With' - Choose Another App

Important - Check the box marked 'Always use this app to open dat . . .'

If Notepad is not in the list, scroll to the bottom and click 'More Apps'

Again if Notepad is not in the list, at the bottom, click 'Look for another app on this PC', then navigate to find the Notepad application in C:\Windows\System32

In your post #16 the 2nd pic is showing an "Unsupported Audio" message.
That suggests to me that your .dat files may be video files.
The zip file you uploaded further suggests they are segments from a video file.
SM player plays the files with a message they were " Created with Nero"
