Thanks Note
I would also thank Elija from thefifthcontinent for alpha testing giis-ext4.
I really thank Toni Graffy, for packaging giis tools for Suse/OpenSuse with appropriate patches and changes.
A Book (especially source codes and examples) by Andrew Krause's "Foundations of GTK+ Development" helped me lot. And a C/GTK+ project which helped me to start Christian Siewert's isprime
Thank you all !!!

Older Versions :

Release Date:June 21st 2009 (For Fedora/Debian/Mandriva) giis_4.6
Above file giis4.6 should work fine for other distro like ubuntu with ext3fs.Any issues please report on below user group.:)
If you are not so keen in using command line,then here comes GUI. "giis-gui" must be used along with above giis tool.It's more like wrapper for above giis binary.(Recommeded to try giis-4.7 that comes with gui than giis-gui-0.1)giis-gui 0.1
Also note UI is at it's initial stage ,so it might miss couple of features(while command line provides those features.) But they will included in upcoming UI versions ;)
Release Date:May 31st 2009 giis_4.5

This tool needs severe testing for linux kernel version = > 2.6 --So wait for few weeks-till the bugs are fixed.

Semantic File Carving tool which recovers gif,jpeg,MS-Word,png,html,java and even MP3 files less than 48KB, if default block size=4kb.Identifying and recovering files based on analysis of file format. This project uses really different concept to recover files.In simple terms,it scans the free area (free bitmap) for magic signatures and if found it marks those (bitmap) address as used and links the contents to a file name.
