Why does the DOS command say that it is not an internal command or that it is not a batch file?

This means that the command you entered (program name) is not in the current directory or system path.

A system path is a directory that you have customized in advance, such as:"c:\dos"

DOS first looks in the current directory, and if it can't be found, then look for it from this directory.

For example, the current directory is d: >

You entered the command ghost

If"d:\"Not in the catalog,"c:\dos", that's when you asked.

When I type in the command dir

At this time, the files in the current d: will be listed, then the dir command will succeed, why, because dir is an internal command of dos, to put it bluntly, it is dos comes with it.

Dos internal commands, such as copy md rd, ren dir cls del echo, and so on.

That is, if the command you enter is not an internal order of the dos, then the program must exist. That's how it can be successful.

This program must be an executable program under DOS, that is, under the parenthestic name. exe .com .bat can only be used as a command.

I'm not here to divide your talents, I think that's detailed enough.

If you still don't understand, then look at the article about DOS, that's all I can write about.

Environment variables: It's okay to set the path value of the command!

When you enter a system-included command in the Run window, it prompts "Not an internal or external command, nor a runnable program or batch file.

, the environment parameters of the system path have changed, and you need to change it to the correct path.

1. "It's Windows Management Instrumentation, Windows Management Tool, the location is in "C: Windows System32 WBEM", find this file here;

2. Double-click to run, so that the system will automatically change the environmental parameters of this command after operation;

3. Go to the running window, enter the wmic command, and the wmic command will run normally.

<> click Enter a description.

My computer right-click attribute advanced environment variable), in the path value, change the path value to c: windows system32

Shen Yi, I didn't do the third step at the beginning, in fact, the third step is also the result of the second step. Later, I tried k f c 1, and it didn't seem to work. Restart the computer, and the third step of Shen Yi was carried out.

It finally worked, although I don't know why it didn't work out at first.

In addition, it is also possible to directly enter the WMIC and then enter the Memorychip.

At first, I wondered if it was because of the 64-bit system, but since it was successful, it was definitely not because of the system. Finally, the system information is attached.

c:\windows\system32\wbem>

See if you have this folder on your machine?

And then see if there is this path in the path?

Reason: In the DOS command window, if the file of the command needs to be executed when the command is run, if the execution file of the command is not found, it will prompt that it is not an internal or external command error.

Here's how to fix it:

Method. 1. Put the dos command execution file directly into the windows-system32 folder, re-run the dos command, and you can execute.

Method. 2. By modifying the execution path method.

1. Right-click on the computer, select Properties, click Advanced System Settings, and click Environment Variables in the pop-up System Properties box.

2. Find the variable path in the system variable of the environment variable, select it and click it.

3. Add the path of the execution command file in the system variable menu.

4. Re-open the DOS window.
