Browser-Based MP3 File Manager for Sony Network Walkmans

This is a project to support MP3 file management on older Sony network walkmans replacing the need for the MP3 File Manager or SonicStage applications.

A guiding principal for this project is to keep the manager (html file) under 100kb in size to maximise storage for music on devices.

Benefits

This manager is a single-page web application in an .html file which leverages modern browser features such as the FileSystem API and WebAudio API.

This approach means:

• It's small (< 100kb). MP3 File Manager is ~600kb, so if you are storing the manager on the device, ~500kb can be reclaimed
• Cross platform. Original software is primarily focussed on requiring 32 bit Windows. This can run wherever you have a modern browser.
• More Features. The manager supports:
  • File and folder uploads (via a file dialog or drag-and-drop)
  • File and folder re-ordering
  • Renaming and deleting
  • Downloading
