About giis:
==========
gET iT i sAY.giis  is a text based file recovery tool.
Once you install giis,files on your disk can be recovered using giis.But Those files which deleted before the installation giis can't be recovered using giis.:-(
**Need to Update?
giis is updated every 20 mintues. To update giis manually try giis -u so that all newly created files and folder get eligiable for recovery.
By default root,home are eligiable for recovery.


How to install:
==============  
Copy giis folder into  /root
Then type, cd /root/giis
Type sh INSTALL	
That's it.

User Guide 
===========
I guess README along with RAQ will be enough.
If you need any doubts or question on giis - just mail me.

LEVEL_VALUE:
===========
Here we have default support of about 12 levels of directory penetrations.
for ex,dir1/dir2/dir3/.../dir12.I hope most files will fall into this range.
If you want level 15, then just reset LEVEL_VALUE to 14.

LEVEL_VALUE is macro found at /giis/giis.h file.


Limitations and Future Versions:
================================
see giis/changelog for more information on versions.
giis v4.1
---------
*Get Lastest version of deleted file:
	-With giis.v.4.1 user can recover last version of a file,if available.
         i.e user can get latest/updated/modified version of a deleted file.
	 This option is available only with giis force - giis dump
*giis analyser :
	- While recover giis analyser try to analyse the disk content so that user can decide whther to recover or not.
*updates :
	- giis updated every 20 mintues.


giis v4.0
---------
*Get by File Type:
	-In giis.v4.0 user can recover only specific type of files rather than all.
	 For example,user can recover deleted .mp3 format or .doc format files rather than all    	   files.
*giis-dump:
	-powerful giis-dump option just dumps the data from hard disk for given file from its 		 older location if the content is modified.
	 But before dumping data it shows sample data from disk and asks user whether to dump 	 	  the current disk data or not.

---------

Advantages of giis.v2.1 over giis.v2:

*Efficient storage mgmt.

in garbage.
