Why aren't my Windows batch files processing when Java executes them?

Question

I have 2 folders, each containing dozens of batch files (*.bat).

The batch files containing text similar to either

del /f/q F:\\MEDIA\\IMAGE99

Code of successful solution used, based on Ian Roberts' answer:

Uses Apache Commons-IO

package com.stackoverflow.windows;

import java.io.File;
import org.apache.commons.io.IOUtils;
import org.apache.commons.io.output.NullOutputStream;

public class Command {

    private Command() {}

    public static boolean batch(File file) {
    
        boolean handled = false;
        Process process = null;
        ProcessBuilder pb = new ProcessBuilder("cmd", "/c", file.getAbsolutePath());
        pb.redirectErrorStream(true);
    
        try {

            process = pb.start();
            IOUtils.copy(process.getInputStream(), new NullOutputStream());
            handled = process.waitFor() == 0;
            
        } catch (Exception ignore) {
        
            // Only throws an IOException we're trying to avoid anyway, 
            // and an expected InterruptedException 
            // handled will be false
        
        } finally {

            if (process != null) {
        
                IOUtils.closeQuietly(process.getInputStream());
            }           
        }
                
        return handled;
    }
}
