How can I loop through all sub folders of FolderA and execute o.bat in each when I execute a.bat?

This should work for you:

for /f %%f in ('dir /ad /b') do start %%f\o.bat

If you need to run the batch file from elsewhere then specify the path to foldera like:

for /f %%f in ('dir /ad /b c:\foldera\') do start %%f\o.bat
