I’m making a script that mixes different videos on screen. The script works if I load the videos from the “data” path, but if i use subfolders like “data/something” I get an error (despite the files are loading correctly):

```auto
finishLifecycleAction(com.jogamp.opengl.util.FPSAnimator$3): ++++++ timeout reached ++++++ main-FPSAWTAnimator#00-Timer0

```

The script to load from folder is a very common one (and is working in both cases):

```auto
String[] files(){

// The data path of the folder to look in (write your own)
java.io.File folder = new java.io.File(dir);
 
// let's set a filter (which returns true if file's extension is .jpg)
java.io.FilenameFilter pngFilter = new java.io.FilenameFilter() {
  public boolean accept(File dir, String name) {
    return name.toLowerCase().endsWith(".mp4");
  }
};
 
// list all the folders inside the main directory
String[] listFolders = folder.list(new java.io.FilenameFilter() {
  public boolean accept(File current, String name) {
    return new File(current, name).isDirectory();
  }
});
 
// list the files in the data folder, passing the filter as parameter
String[] filenames = folder.list(pngFilter);

return(filenames);
}

```

Any ideas? Somehow opengl won’t like files from a location different to “data”. This is nuts.

The standard 1 is called “interactive sketch”, in which we can have the callbacks setup() & draw().
