Java: open a folder when a button is clicked

Question

In java, how can we open a separate folder (for example, c :) for the user at the click of a button, for example, like “find this file on disk” or “open folder with folder” when we upload the file and we want to know where it has been saved. The goal is to save user time in order to open a browser and find the file on disk. Thanks (the image below is an example of what firefox does)

I got the answer: Here is what worked for me on Windows 7:

File foler = new File("C:\\"); // path to the directory to be opened Desktop desktop = null; if (Desktop.isDesktopSupported()) { desktop = Desktop.getDesktop(); } try { desktop.open(foler); } catch (IOException e) { } 

Thanks @AlexS

I assume you have a file. With java.awt.Desktop you can use something like this:

 public static void openContaiingFolder(File file) { String absoluteFilePath = file.getAbsolutePath(); File folder = new File(absoluteFilePath.substring(0, absoluteFilePath.lastIndexOf(File.separator))); openFolder(folder); } public static void openFolder(File folder) { if (Desktop.isDesktopSupported()) { Desktop.getDesktop().open(folder); } } 

Be careful if you call this with a file that is not a directory, at least Windows will try to open the file with the default program for the file type.

But I do not know on which platforms this is supported.
