make data unrecoverable

[saj_amo]

hi friends

plaese help me i want to know how i can delete data permanently so that it can not be recovered from any software is there any way to do this ??

Format the disk, the easy way is to overwrite all of the data with other data (just takes a long time), but if you have some coding skills just write some software that creates a file and bloats it with zeroes (NULLs). other than that, you can just copy some bull**** data (like pr0n) until the disk is full, defragment and reformat. That way, if anyone tries to recover your data, all they see is the nonsense data you overwritten the sensitive data with.

Have a look here, but I've never used it

Your firewall, AV or cleaning softwares likely have tools inside their Options tab to do just that job for you.

You can just secure erase it. So that the file will be delete securely and no trace will be remain on your hard drive. Nobody use reformat to delete only a file. Like what gerbil and bal had said, they are a better option then reformating your disk.

jingda : i think you get my point i don't want to erase whole drive i just want to delete particular file or folder which i want not to recover by any one.

katmai539 : thanks alot but i want to remove only some data so how i can overwrite other data? is that other data should be of same size or space ?

[jingda]

Have you follow the suggestion made by me, gerbil and bal. Don't follow katmai advise, he has no prior experience to this. Good luck.

delete all the files ... empty recycle bin and then remove registry traces of the file you can use RegInOut to remove registry traces... download it from here.. www.reginout.com this will permanently delete the file..

For those who use ccleaner and probably mentioned here.

Now you state you want just files and folders, see above

Thanks to all who are trying to help and yes, some AV Security full editions do have the eraser's as Utils.

jingda i'm sorry to tell you, i've been doing some recovery work for big instances and i do have 'some' experience with data-requisition and perma-removal. I must've misunderstood the initial post. I thought saj_amo wanted to clean a whole disk. I understand the negative vote you gave me but please don't state things on people you don't know.
Best regards though.

USe glary utilities and delete your file using that, it uses military standard algorithms to delete your file.
