Need help Encouding .dat file

[colddevil99]

Hi all,

I'd a WexEx online training recording. It has been expired now. But luckily I could collect the ashes of my training sessions to rebuild entire session once again and i got success too.

I've collected these files after completion of the video by this method,

%windows%\Users\%username%\AppData\Local\Temp\<sev eral digits>

the files are,



Then I've rebuild entire training session from these files through tool WebEx rebuilt. downloaded from here

But the problem is I do not have sounds in my file. This tool need .wav sound file and all the Webex free webinar has this file available but unfortunately my one doesn't. What i got is .dat and .idx file. i need to decrypt it to get my .wav sound file.

How would i able to do it? i've just tried everything possible within my knowledge.
