How to permanently delete files from my system?

Question

Hi....recently one of my friend gave me a file recovery software....

When I run the software...I was shocked :O

It is recovering all deleted movies, songs games which I deleted years ago....and all are working fine except some files...

All I need is "How can I permanently delete files from my system?" such that no file recovery software should recover again...I want to completely delete that deleted files from my system and I don't want to restore them again..


Best answer is appreciated...:)

Answer 1

If you believe me then its possible to recover even if the hard disk sector is over written few times..

If you permanently want to delete the file then you need to use so called file shredder. You already got few names..

Remember there are ways to recover complete history of the HD sectors by use of proper tool. Not all shredder are capable of stopping advanced recovery tools to recover your HD's history.



In case you simply want that you should not be able to recover any deleted file using un-delete software then you can simply backup the drive, format and restore. After these simple steps no un-delete software will be able to recover your deleted file..

you must note that file shredders write to same sector multiple times(with random data) multiple times... which may decrease life of your HD if you use it too frequently. Shredders are basically used to nuke project/Company related data which can not be risked(like company provided laptops)..

Someone ought to tell Jack K(answer) that Nothing is permanently deleted on a hard drive without a great deal of trouble. All deletion does is remove the reference to the file in the file allocation table of the file system. It takes hours to wipe data permanently off a hard drive. Even when undelete programs(search Yahoo) cannot recover a file it is because they can't find contiguous blocks or sectors not because the file isn't there. How did you permanently delete them? Are you sure they are not in the recycle bin? file recovery programs will not find files that are still recorded in the file system.

Answer 3

Well, I don't see WHY you would want to do that, but i'll just answer your question anyways. Normal file deletion simply removes the header for the file so the harddrive doesn't 'see' it anymore. Because of this, new data can be written over the space that the older data was written on. Actually, the new data is written on TOP of the older data, similar to a compost pile. What you want to do is what techies call 'Writing zeros' to your hard drive. This process writes zero byte data onto all the sectors of your hard drive, physically clearing the 'compost'. It returns to the state it was when you first bought it. It's a lengthy process, and you would only really benefit if you need sensitive data completely wiped from your system.

Answer 4

When data is saved, it gets placed in a certain location on your hard drive, and Windows keeps a list of where everything is saved. When you delete something, Windows removes it from the list so that it can no longer be seen or accessed (by regular methods), but the data is still sitting there in the same place on the hard drive, just Windows doesn't know it's there.



Recovery software checks your hard drive for filled locations to find deleted items that Windows no longer can see.



Using a program like the one suggested above will overwrite all of those filled locations with a very small piece of data. Once something new (the small bit of data) is saved over a location, whatever used to be there is gone for good.

Answer 5

When data is saved, it gets placed in a certain location on your hard drive, and Windows keeps a list of where everything is saved. When you delete something, Windows removes it from the list so that it can no longer be seen by you.

After deleting the file permanently you have to run "Disk Cleaner" it will delete the files from hard disk.









NOTE:- Windows remains a copy of all your programs. This can be cleared only by running "Disk Cleaner".

If u r using vista or 7 os then u can search for "Disk cleaner in ur programmes."

Answer 6

When you delete a file, all that happens is that your OS stops reading the file because the file headers are removed. The complete file itself is still present on the hard disk. When you use a recovery software, it reads the disk, not what the OS thinks. The only way to erase is to overwrite the file with special patterns. To do this, a free, GPL licensed, software is available called Eraser.

Answer 7

your best bet is to install ccleaner (www.ccleaner.com)

Check all boxes at the right and delete all unnessary files first

the very last box at the bottom is to clear free space where deleted files reside. Check in options/settings to wipe free space. Use 35 passes under secure file deletion.



It will take one hour to perform but run this recovery software after and see by yourself !



And since you already are in ccleaner interface, check the registry repair options and use JKDefrag 3.36 to defrag your disks AND registry

Answer 8

i use CCleaner, you can change the settings to "secure deletion" which makes up to 35 passes of everything it deletes, and you can wipe your free space. its a free program, used to maintain your computer, it cleans the registry and deletes temp files, so its very useful, and it'll securely delete and wipe free space every time if you check the box, its a very useful program, besides providing secure deletion.



it overwrites a file up to 35 times when you delete it, just to give you an example of how secure that is, the NSA only makes 7 passes.



an entire wipe only takes about 15 minutes for me, and you can still work with it running, but it takes a bit of cpu.

Answer 9

If u r desperate abt it then u can manually do it by

overwriting every bit of memory ur hard disk has with some data(anything).



This will overwrite the memory where your files were saved

and ur files will be permanently deleted.

Answer 10

Look for a program that "Incinerates" a file...Makes it un recoverable...Systems mechanic by iolo has a function that does this...Delete just removes the reference to the file and leaves the file...(Makes it invisible to the system)...Incinerate actually wipes over the data in the file...putting random 1's and 0's to destroy the data and make it unrecoverable...you can probably fine other versions of this ...

Answer 11

Welcome to the club “delete” does not mean “erase”. What you are looking for is call file/data shredder, some free options are:

• Spybot includes under its tools a secure shredder (Spyware it is also a antispyware) http://www.safer-networking.org/en/index.html

• Eraser http://eraser.heidi.ie/

• Free File Shredder http://www.fileshredder.org/

Answer 12

derick's boot and nuke...



that wipes the whole, whole drive...



the thing is when you delete somthing it doesn't delete at all, it puts it in a sub directory to be put in a que for overwriting...it says hey this space is free and when you add stuff it will over write it.



if your worried about data being stolen, a high powered magnet will perminially make your hard drive wrothless...



dont' worry about it though, most times it shouldn't matter what is still on your computer or not.

Answer 13

http://eraser.heidi.ie/ Eraser is a free program that permanently deletes files.

Answer 14

you can go to the main switch, which holds all your information. that would have to be hacked into but it wouldn't take much. but there are other ways i guess. i just think you should no that no whatever what you do. your files are never deleted off your computer. everything is saved on your hard drive. that's why your computer has saved files from years ago.

Answer 15

Well u could try deleting them again ir u could try finding some Other way i would do that or take it in to like staples or some thing depending on the computer

Answer 16

David beat me to it: Eraser is awesome, and does exactly that. It's not quite as intuitive as it could be, but f your IQ is above 100, you shouldn't have too much trouble with it.



Oops! It seems Ganesh D also beat me to it! (I type sloooowly)

Answer 17
