E.G:

void setup() {
selectOutput("Save *.txt:", "fileSelected");
}

void fileSelected(File selection) {
if (selection == null) {
println("Window was closed or the user hit cancel.");
} else {
// println("User selected " + selection.getAbsolutePath());
}
}

Search JFileChooser in the forum (or on the site, more results). It is a Java component (some extra imports will be needed) with more flexibility in the options. If you use it outside setup(), you have to wrap its call with noLoop() / loop(), I think.

hello, I studied a little item on the library "JFileChooser".
but I could not do the filtering to only show me the files
with the desired extension.

give me a hand?,

import javax.swing.*;

// set system look and feel

try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
e.printStackTrace();

}

// create a file chooser
final JFileChooser fc = new JFileChooser();
// fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);///.FILES_ONLY
// fc.setFileHidingEnabled(false);   ///show hidden files
//int returnVal = fc.showDialog(this, "Attach"); /// //name

int returnVal = fc.showOpenDialog(this);
// int returnVal = fc.showSaveDialog(this);

if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();

// see if it's an image
// (better to write a function and check for all supported extensions)
if (file.getName().endsWith("jpg")) {
    // load the image using the given file path
    PImage img = loadImage(file.getPath());
   println("caca");
}
}

Ah, there is a question in your previous post? I thought you just shown a library you found...
Have you tried to use:
chooser.setMultiSelectionEnabled(true);
?
