Execute batch files in subfolders at same time

Hi everone,

I have 3 subfolders in the Hyperstudy directory. Each Folder contains one .bat file.

I want to run all these (.bat files) at same time from m_1 by giving batch file to Hyperstudy.

Here is the folder structure for better understanding.

 m_1
 -abc.bat
  Subfolder1
  -a.bat
  Subfolder2
  -b.bat
  Subfolder3
  -c.bat 

So the batch file in Directory m_1 sholud be able to run all the batch files in subfolders at same time.

Is there any way I can do that.

PS: I tried with ' for ' command but Hyperstudy does not work.

Thank you for your help in Advance.

regards,
