del *.*　　　　Delete all files in the current directory

[Suggestion] Using del *.* in the root directory of drive C will make the computer unable to find the mouse, CD drive, cannot use Windows, and even cannot boot. In fact, when using this command in any directory, you need to think carefully.


deltree *.*　　Delete all directories and files under the current directory

[Suggestion] When using this command in the root directory of drive C, you must ensure that your mind is clear, and you ensure that it is necessary to do so, but we think that you should not use this command in any case. Using deltree *.* in any directory will produce the same or even worse results than del *.*. Be careful! Be careful!

format c:/u 　　Format drive C

[Suggestion] Unless your hard drive is deeply infected with a virus, or a real computer expert tells you that you should do this, do not format drive C. It will make you lose all information, and you will need to spend several hours reinstalling all software.

　fdisk 　　　Hard disk partitioning

[Suggestion] When partitioning the hard disk, be sure to let someone who has used this command help you use it, otherwise you will lose all information, and even the hard disk cannot be used.

　recover　　　Overwrite the disk

[Suggestion] This command is no longer available after DOS 6. If you are using an older version of DOS, it is recommended that you do not use it at any time. It has no other function except destroying all information on your hard disk.

Thanks to the LZ's reminder~~ This is indeed a very influential command

Some things are no longer used. The system just doesn't have them.

Well, these commands really need to be used with caution.

Got it. Thanks to the楼主

These commands are very dangerous, but in some cases, this command is still very useful. For example, to delete files in a certain directory (folder), you need to use the del *.* command. My suggestion is that if you want to learn these commands, it is better to do so in a virtual disk.

Thanks for the reminder from the LZ!

Thanks from the bottom of my heart!

Thanks to the LZ for the reminder　Got it　Hehe

Thanks to the LZ's reminder~~ This is indeed a command with strong influence

Learning...

Thanks for the reminder, I'll be careful in the future
