Hello everyone, this issue will teach you a practical little command, is to completely delete the data on the hard disk , and the hard disk recovery software cannot recover it!
I believe everyone knows that the photo dissemination incident that shocked the entertainment industry back then was because the computer was taken to the computer company for repair, which led to the recovery of the hard disk data, causing a series of troubles!
is a household name. Whenever I talk about it, I will think of that classic saying, is very stupid and naive during the day, and very... at night!
After this incident, everyone is very cautious about files on the computer. So today I will teach you a trick to completely delete files on the computer!
is a very practical small command, please accept it!
. Run the cmd window as an administrator and open cmd as shown in the figure below:
2. In the command prompt window, directly enter cipher /w: path , enter this command plus the path to completely delete the file!
You can see from the entire command description that data is deleted from the unused disk space available on the entire volume.
For example, if you want to prevent the F disk data from being restored, you just need to enter cipher /w:f!
As can be seen from the figure, it needs to go through three steps. first writes to 0x00, writes to the remaining space, then writes to the data 0xFF, writes to the remaining space the second time, writes to the remaining space with random numbers, and the remaining space is written three times, even if you use any recovery software, you can recover the data!
is very powerful, but it is recommended that you use it with caution, because if you really delete any data by mistake, you can't recover it in the future!
So, do you know any other useful cmd commands?
. That’s all for sharing computer skills in this issue. They are all very practical and simple tips. I hope you like it. We will share a piece of computer skills in each issue later. Thank you for watching, thank you!
