Get to Know Permanent Deletion of FilesWhat is file deletion exactly? In fact, it refers to the process of removing file from file system, making it disappear from computer. We often choose to delete files in order to release more free space, protect private information or avoid confusion.

After knowing it, you’ll have a clear understanding of why deleted files can be recovered and how the recovery is achieved.
File Storage on Hard Drive
To know the actual changes of hard drive after file deletion, we must know the storage of a file on hard drive at first. In Windows OS (Operating System), a hard drive is divided into 5 areas: MBR, DBR, FAT, DIR and DATA.
MBR (Master Boot Record): generated by Fdisk – the partitioning command, it is located in cylinder 0, head 0 and sector 1. When you see "55 AA", you should know it’s the end of MBR.
DBR (Dos Boot Record): generated by formatting command, it is located in cylinder 0, head 1 and sector 1. It’s the first sector that OS could have access to. It includes a bootstrap program and a BIOS parameter block.
FAT (File Allocation Table): in Windows, a file is actually divided into several segments and each segment is saved into dispersed hard disk clusters. The connection information among different segments is saved in FAT. So when accessing a file, the system can find certain segments quickly and accurately according to records in FAT.
DIR (Directory): this area is also known as FDT (File Directory Table), which records the information of each file (directory), such as starting & ending unit and attributes, in the root directory.
DATA: this is the exact place where the real content of files is stored.
What Happens When Files Are Deleted
So, what’s the real story for file deletion?
As a matter of fact, when files are deleting by system, a deletion mark will be placed onto their file directory entries. Then, the clusters occupied by them in FAT will be marked as empty and available for use.
At this time, there’s no change made to the DATA area. So, to sum up, it is the certain information in FAT/FDT that has been destroyed when file is deleting; the real content still remains intact.
Reasons for Deleting Files Permanently
Once a file is saved to hard drive, it’ll always be there until we choose to delete it or unexpected accidents occur to remove it. Well, do you know the reason why we want to delete files permanently? If not, please take a closer look at the following possible reasons.
Release free space: as the data we store in computer or other storage devices is increasing rapidly, the demands for large capacity and frequent backup are also increasing. This leaves great pressure on both individuals and enterprises. Thus, file deletion is a good way to relieve the pressure.
Avoid confusion: when we have many files with similar names, we may choose to delete the unnecessary ones to avoid confusion. Or when we have a few modification versions of a file, we’d better delete the useless ones to avoid misoperation.
Protect sensitive data: for both individuals and companies, they may save files include personal information, bank account and other sensitive data in computer hard drive or removable disk when they need to use them. For safety considerations, they’ll delete those sensitive data after using them.
Avoid privacy leakage: when we plan to sell our computer/other equipment, we need to firstly check whether it contains any confidential data. If it has, we must delete them permanently before selling to stay away from privacy leakage.
Well, the real problem appears – how can we remove files permanently?
How to Permanently Delete Files on Windows & MacHere, we summarize the ways people often used to permanently delete files on both Windows and Mac.
Permanently Delete Files on Windows
If you are running a Windows system, you may be familiar with the permanent remove process of data from hard disk. Why? That is because permanent file deletion on Windows is frequently talked about and you can easily find related posts on the internet.
There’re 4 common ways that are adopted to delete files on Windows.
1.Select the files needing to be deleted -> press "Delete" in keyboard (or right click on the files and choose "Delete") –> find Recycle Bin and right click on it -> choose "Empty Recycle Bin".
The last two steps are not necessary when the files we choose to delete are saved in removable disks connected to computer, such as external hard drive and memory card.
2.Select the files needing to be deleted -> press "Shift" and "Delete" in keyboard at the same time -> choose "Yes" in the pop-up prompt window.
3.Open Windows Disk Management -> select certain partition under Disk Management -> right click on it and choose "Delete Volume…". (You can also make use of third-party software like MiniTool Partition Wizard to delete partition)
4.Open Windows Disk Management -> select certain partition under Disk Management -> right click on it and choose "Format…" to clear data. (You can also choose to format the partition/disk by using Diskpart command).
Here’s how to recover data after diskpart clean if you made a mistake.
Permanently Delete Files on Mac

Recovering Permanently Deleted Files from Windows & MacTo be honest, data security has always been the issue that we are concerned about. But, file deletion can be a security "bug" that is relatively easy to be ignored by people.
As we said, after file deletion, the real content will not be removed immediately. By analyzing related information, data recovery software is able to bring them back.
Obviously, this tends to cause privacy leakage to individuals or serious losses to companies. Yet, as every coin has two sides, this also leaves a second chance for people who deleted files permanently and then want to recover deleted files from memory card, USB flash drive or hard drive.
We suggest users who want to sell storage device to other people to wipe data completely, instead of just deleting them (they can choose professional tool like MiniTool Partition Wizard or choose to write in and delete new data repeatedly to erase data completely).
And we suggest users who want to recover permanently deleted files to stop using the drive immediately after finding themselves made a mistake.
