Default >tec & .arc files

Its my exp. Previously i installed a vault apps on my galaxy N7000. Later i upgrade it from ICS to jB. After that i found that i lost my pics & clips which were in vault. I thought the files must be on my phone, so do lot of search. I found few tec & arc files. I think that these are the pics & clips which saved in vault. I also doughtfull that this vault only changes the ext of pics & clips. But i dont understand how to recover the files?

They can be deleted and do not affect your current photo's that you have on your phone.

Default hello!

Hi I'm kwegs! Sorry for the stupid post, wouldn't let me add anything of substance in my initial post. Had to do an intro, I'm guessing most of you knew this already. Anyway, Hello and thanks in advance for any advice you can offer.

Notsure Lost Pix!!!

So does anyone know if it is at all possible to retrieve the data in these files? My husband just lost every pic he had of our 2 week European cruise. We've been to Sprint, Best Buy, an independent computer guy and everyone said he was SOL. We even asked a cop friend about phone forensic specialist that could possibly help. Then today he found these arc and tec files. Any hope of getting these opened to retrieve what's been lost?
We do have the Samsung Galaxy SII's btw.

Default Image Recovery Tool

My Uncle had this problem, and I found a way to recover the files. The .tec file has the same pixel density as the original .jpg, only in the wrong format.

I've written a Java program to automatically restore the files. You can get it from my website here: thebillington

Hope this helps if you still have your .tec files!
