For those who want the fixed Linux support: Please download the prebuilt native library from this repo and replace the corresponding file in your project after importing the original Unity package (Unfortunately I don't know how to make a Unity package).

The prebuilt native lib is Assets/StandaloneFileBrowser/Plugins/Linux/x86_64/libStandaloneFileBrowser.so.

You can also build it by yourself. The native Linux library's code in under Plugins/Linux/StandaloneFileBrowser. Make sure you have GTK+'s headers installed and run make (NOT cmake) to build it.

Technical details: The original code loads GTK+ inside the Unity process. It causes the gtk_init function to hang in a deadlock (See the backtrace here). I separated the GTK+ related code to a new executable (I'm not sure about Unity's directory structure so I bundled the executable in the library) and run it in a separated process (pass input with argv and get output from pipe()-d stdout) when opening a dialog.

Unity Standalone File Browser

A simple wrapper for native file dialogs on Windows/Mac/Linux.

• Works in editor and runtime.
• Open file/folder, save file dialogs supported.
• Multiple file selection.
• File extension filter.
• Mono/IL2CPP backends supported.
• Linux support by Ricardo Rodrigues.
• Basic WebGL support.

Download Package

Example usage:

// Open file
var paths = StandaloneFileBrowser.OpenFilePanel("Open File", "", "", false);

// Open file async
StandaloneFileBrowser.OpenFilePanelAsync("Open File", "", "", false, (string[] paths) => {  });

// Open file with filter
var extensions = new [] {
    new ExtensionFilter("Image Files", "png", "jpg", "jpeg" ),
    new ExtensionFilter("Sound Files", "mp3", "wav" ),
    new ExtensionFilter("All Files", "*" ),
};
var paths = StandaloneFileBrowser.OpenFilePanel("Open File", "", extensions, true);

// Save file
var path = StandaloneFileBrowser.SaveFilePanel("Save File", "", "", "");

// Save file async
StandaloneFileBrowser.SaveFilePanelAsync("Save File", "", "", "", (string path) => {  });

// Save file with filter
var extensionList = new [] {
    new ExtensionFilter("Binary", "bin"),
    new ExtensionFilter("Text", "txt"),
};
var path = StandaloneFileBrowser.SaveFilePanel("Save File", "", "MySaveFile", extensionList);

See Sample/BasicSampleScene.unity for more detailed examples.

Notes:

• Windows

  • Requires .NET 2.0 api compatibility level
  • Async dialog opening not implemented, ..Async methods simply calls regular sync methods.
  • Plugin import settings should be like this;

  

• Mac

  • Sync calls are throws an exception at development build after native panel loses and gains focus. Use async calls to avoid this.

WebGL:

• Basic upload/download file support.
• File filter support.
• Not well tested, probably not much reliable.
• Since browsers require more work to do file operations, webgl isn't directly implemented to Open/Save calls. You can check CanvasSampleScene.unity and canvas sample scripts for example usages.
