:( Where has it gone?..

If you cannot see it anymore then it was deleted. A lot of times mylot has been deleting similar topics. Why not go to his profile and search his activity!

well can I know in description..?? you were working something means what? you lost just documents? or something codes? you can get your documents which were deleted or not able to find via recovery softwares.. other work I am not getting..

Well I hope I can help, but sometimes folders are really lost, depending on the damage. I am assuming that your netbook is working again. If depending on what operating system you are working on do a search for the folder in the core. For windows you can try this http://www.educationworld.com/a_tech/techtorial/techtorial050.pdf for Ubuntu these may give a clue of which path to follow http://ubuntuforums.org/showthread.php?t=1248006 or http://karuppuswamy.com/wordpress/2010/06/09/how-to-recover-files-from-lostfound-after-fsck-in-linux-how-i-did-it-in-ubuntu/ I hope you recover your files, it is incredibly annoying and frustrating loosing work so I hope it works out. I know this is a bad time to mention it but may I suggest that you buy a storage pen to keep the most important things in case your computer has issues, I learnt my lesson after it happened a few time.

Awww that's really disappointing,, it happen to me most of the time. But anyway try to search it in any way you can. Hope you can retrieve those files =)
