Get to Know Permanent Deletion of Files

What 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.

Well, it’s not difficult to discover the fact that – we can easily undelete files with the help of data recovery software like MiniTool Power Data Recovery. And the tutorials on how to recover your deleted file are everywhere on the internet.


But before we show you the detailed steps to recover data, we guess you may be curious about what really happens when you delete a file. So, that’s what we’re going to tell you in the next part. 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 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 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 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 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 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.


reason1 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.

reason2 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.

reason3 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.

reason4 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.

Recovering Permanently Deleted Files from Windows & Mac

To 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.

note Note:
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.
