windows - How to run multiple batch files with one master batch file

I have three bat files I would like to run, in three different directories:

directory/bat1/bat1.bat

directory/bat2/bat2.bat

directory/bat3/bat3.bat

I would like to use one master .bat to start all of the other bats in their directories. I can't use call because I get errors because there are dependencies for each different bat in the directory. I tried using start but that doesn't work either, it just bring up a command prompt withing the folder.

I know this sounds a little confusing but all I want to do is use one single .bat file to run multiple .bat files independent from each other in their own directories.

Answer

I found a solution! I used this code in order to get the bat to open the three different bat files independently:

cd "\directory\bat1\"
start bat1.bat
cd "\directory\bat2\"
start bat2.bat
cd "\directory\bat3\"
start bat3.bat
