You don’t need **split()** for parsing paths! Just use methods from Java’s File class: 📂  
[Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/io/File.html](http://Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/io/File.html)

Along w/ some methods from class String: 🔤  
[Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/String.html](http://Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/String.html)

```java
final File f = sketchFile("img.bmp");
println(f);

final String folderpath = f.getParent();
println(folderpath);

final String file = f.getName();
println(file);

final int idx = file.indexOf('.');
final String filename = file.substring(0, idx);
println(filename);

final String ext = file.substring(idx);
println(ext);

exit();

```
