deCHK

A free program to regain/recover chk-files with windows os


(c) 2009 by Sascha Presnac

About this program

After the last crash of my hard-disk i was able to recover about 5,900 files with 'chkdsk', but this files all ends with .chk and were placed in a directory called 'found.000'. Now, i figured out that these files are still my files i lost, but windows do not know the extension '.chk'.
So, i wrote this small tool, with was able to recover about 80% of my files. Especially, i am happy that i made it to recover all our family-photos completely.

And: Yes, i consulted some search engines befor i started typing, but there were only 4 tools i found and none of them was able to regain more than only some few file - and for that, they all spend more time than my deCHK *g*
