Can't execute batch file without extension

Hi,

 

I have this batch command problem and don't know how to resolve it.

 

For example, I have a batch file called mytest.bat.

 

It works if I double click it in Windows Explorer

It works if I type mytest.bat in DOS Window

It does not work if I just type mytest.

 

I can't find any reference to this problem. I hope somebody can point me out

on this. This prevents me from doing lots of stuff.

 

Thanks,

What do you see when you do this:

1. Create the file c:\MyTest.bat

2. Put this line inside:

echo Hello world.

3. Open a Command Prompt (Click Start / Run / cmd {OK}

4. Type this command:

c:\MyTest {Enter}

Thanks for the reply,

 

It says:

 

C:\>mytest

'mytest' is not recognized as an internal or external command,

operable program or batch file.

Re: Can't execute batch file without extension

 

Your %pathext% lacks the .bat component. You need to restore it here,

then reboot the machine:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

 

You can test this immediately by renaming your batch file to

MyTest.cmd. Does this work?

Re: Can't execute batch file without extension

 

Thank you very much.

 

I changed that from environment variable table. It works now. I am wondering

how has that happened. I don't believe I have ever touched pathext before

from neither environment variable nor regedit.

Re: Can't execute batch file without extension

 

Congratulations!

By thinking of the time when it happened, you can probably

work out "who dunnit", e.g.

- Some software installation

- Malware

- Virus infection

- Someone else playing with your machine

- You playing with your machine
