Stopping operating the computer leaves great chance to recover permanently deleted files in Windows 7 or other systems

1. This Tool Can Recover Permanently
Deleted Files In Windows 7
File deletion is a common and necessary computer operation. There is almost no
computer user who has never deleted a file from computer before. Undeniably, it is a
convenient way to help you get more free space for new data. Also, it is regarded as an
easy solution to protecting privacy. Most of the users wrongly hold the belief that once
they deleted the files in which privacy is involved, they’re able to prevent other people
from seeing it. Let’s face the truth: even permanently deleted files can be recovered with
special methods. So please seek for more reliable ways to destroy the files you would
never want to share with others.

We suggest you to break the storage device with useless confidential files into pieces or
burn it to ashes. But you also need to pay attention to one thing before you decide to do
this: confirm repeatedly that the files contained in the device are no longer useful. That is
because once you finish breaking or burning it, all files will be gone forever. You never
have a chance to regret. There’s also another important factor – if your storage device is
very expensive or you’re not ready to give up on your device. In this case, you are advised
to try other means of permanent file deletion to achieve your goal. As for the deletion
methods, we’ll mention in later content.
Recycle bin in Windows is indeed a sweet design for any false deletion. If users delete
files by choosing “Delete” after right click on them or pressing “Delete” button in keyboard
after selecting, files will be sent to recycle bin, instead of moving out from computer. No
change is made to the deleted files in Windows recycle bin. This leaves great chance for
users to regret. In this way, users can get back those files anytime they want as long as
the time does not exceed the maximum limitation. By the way, you can modify the property
of recycle bin to change the limitation.
How to Delete Files Permanently in Windows 7

2. When you plan to remove some file permanently from
computer, of course you are unwilling to see deleted files being recovered by any data
recovery software. In fact, the easiest way to achieve your goal may be filling the partition
(which includes deleted files) with unrelated files. In this way, you can complete a memory
overwriting operation. And at this time, many data recovery tools will be useless.
Accordingly, it becomes even harder for users to recover permanently deleted files if
they find deleted data are actually useful later.
Let’s make a metaphor: you write a word in a piece of paper in case that you may forget
when you need to use it. After using, you don’t want others to see this word. At this time,
writing a new word in the same place to cover it may be a good choice. Once this work is
done, it becomes harder for users to figure out the original one. But imagine this, if you
repeat the overwriting process for several times, who can tell exactly what the original
word is.
In summary, the following ways can all be adopted to delete files permanently:
 Delete files through pressing “Delete” in keyboard after selecting them or you can
choose “Delete” from the pop-up menu you see after right clicking on chosen files. Then,
those files will be sent to recycle bin and you still need to empty it to complete
permanent deletion of file.

3.  Choose the file or files you want to remove completely from computer, right click
on it to see a pop-up menu, choose “Delete” from it (this part is similar to above method)
and press “Shift” button in the keyboard at the same time.
 Press “Delete” (also shown as “Del” or “delete” in some computer keyboards)
button and “Shift” button in the keyboard simultaneously after selecting all files needing
to be deleted.
 Delete by using DOS command: since Windows Recycle Bin only records the
content of files deleted under Windows, so we can delete a file permanently in pure
DOS mode or Windows MS-DOS mode to stay clear of recycle bin. You are allowed to
enter MS-DOS mode to delete a file through Del or Deltree command.

4.  Change the properties of recycle bin to make the files not been sent to recycle bin
when deleted. There is one simple way available for all of you:
Right click on “Recycle Bin” icon on desktop -> choose “Properties” from pop-up menu
-> choose “Don’t move files to the Recycle Bin. Remove files immediately when
deleted.” under “Settings for selected location” -> press “OK” to confirm changes.

5.  In Windows OS after Windows 2000, there exists a built-in tool, the name of which
is cipher.exe. It can be used to delete files permanently in an easy process: in general,
we only need to type “cipher/W:F” (F refers to the letter of drive from which you have
deleted some files). Then, 0x00, 0xff and arbitrary figures will be invoked to cover the
entire partition free space so as to eliminate any traces of deleted files. It is worth noting
that this way can only be applied to NTFS drives.
 File crushing function has been integrated into some third-party tools to help users
delete a file permanently. So users can choose a powerful one to achieve reliable
deletion.
 Formatting is usually a frequently used way to initialize a hard drive or partition.
After formatting, all files in it will be deleted. And it seems that all files will be removed
after drive formatting.
 If users plan to delete all files in a partition, they can also delete the whole partition
conveniently to realize the same result.

6.  A safer way to move all data out of computer is wiping. Disk wiping can erase all
data in the whole disk while partition wiping aims at erasing all files in a single partition.
(Files deleted by wiping method are more difficult to recover. If we perform wiping for
enough times, we can make the data can’t be recovered.)
By the way, MiniTool Partition Wizard is a good choice to wipe disk or partition. Please
activate “Wipe Disk” or “Wipe Partition” function according to needs.
 Copy the name of file you want to permanently delete. Then, create a new file of
the same type in another place and name it with the copied name. After that, you need
to move the newly created file to the location in which the target file locates. At last,
choose to replace the target file with the new one. (Make sure that the suffix name of
both files should be exactly the same.)

7.  You are able to use this method to delete some business documents to prevent
file recovery to some extent: click “Start” button -> type keywords in target document
name into the textbox of “Search programs and files” -> click “See more results” ->
select all files you need to delete and execute deletion -> empty recycle bin -> use new
files to cover the space originally taken up by deleted files -> set about disk
defragmentation.
If you are a Windows 8/8.1 user, the work to completely delete files in hard disk will
become much easier since in the latest Win 8 system, there is an initialize computer
function. It can enhance security of computer hard disk data so as to prevent others from
recovering permanently deleted files easily with data recovery software. The working
principle of this feature is: writing data randomly into the hard disk with deleted files so that
traces of the deleted files will be erased. This greatly increases the file recovery difficulty.
However, believe it or not, some people can always find practical way to restore directly
and permanently deleted files or recover files deleted from recycle bin. So please be
particularly careful when private data is involved.

8. What Really Happens during File Deletion
Figuring out the changes of files after deletion could be very useful for us to recover
permanently deleted files. According to information, “directory area” and “data area” will
be generated automatically after a hard disk has been formatted. As its name shows,
“directory area” is responsible for saving location and other information about data saved
in data area; while “data area” is actually the place where the data locate.
When we complete the so called permanent deletion, system will mark a “deletion tag” on
the information of certain files so that the space occupied by them could be released as
available in system. This place may be employed when new data are writing into target
disk or partition. Once the old files are covered by new data, the possibility of successful
data recovery will be decreased.
Because of that, those hard disks with personal or business critical information often
become the hunting target of hackers. Some professional hackers will even find
companies’ waste hard drive on purpose, trying to recover some confidential data to reap
huge profits. As a result, please remember not to discard or resale the device which was
used to store important information. Even if you thought all files in it are permanently
deleted, it is usually not the case.
In fact, files are stored in the hard disk in a small unit called cluster and corresponding
data are generated to record the cluster entry number of each file. This is a little bit like a
chain. Once you discover the first section of the chain, it becomes easy for you to find all
related files. Of course, you have to be equipped with rich knowledge and experience to

9. accomplish such work.
When a file is deleted, it is only the using state of clusters (which are occupied by the
deleted file) in file allocation table that will be changed from “used” to “available”. The real
content of file still remains all the same. Taking advantage of this point, some data
recovery tools, like MiniTool Power Data Recovery, have the ability to find back all files by
collecting information in clusters. However, as we mentioned before, data may become
unable to be recovered if they’re overwritten by new data.
All in all, you should avoid performing any unnecessary operations to computer right after
you notice the data loss if you want to finish deleted files recovery in Windows 7 or other
systems. On the contrary, if you want to delete all files in a device and don’t want others to
recover them, you must be 100% sure about the fact that files has gone forever.
Possibility for Permanently Deleted Files Recovery in Windows 7
Basically, whether a Windows 7 user can recover files deleted from recycle bin or not is
closely related to the successful rate, which varies from case to case. Here is something
we want to talk about recovery possibility.
Firstly, you may try your best to confirm the time of file deletion. If you realize that
permanently deleted files are useful right after the deletion, you have a great chance to
get them all back. In this case, you’re supposed to take actions to recover permanently
deleted files as soon as possible.
If several days or months have passed and now you finally realize the wrong deletion, the
possibility of files recovery in Windows 7 mainly depends on whether new data are written
into hard drive or not and whether deleted files are covered by them. No matter what the
result is, you need to carry out operations to try to recover files anyway.
