I have just published my open source Android File Share application.
FileShare allows you to share files on your Android phone with any device capable of browsing web pages and downloading content (other Android phones, iPhones, Desktops).
You create Shared Folders, and put content into those Shared Folders. In the future, it will be possible to password protect these folders so you can share content with specific users or groups.
You can download the application on your Android from the Android Market Place. Try searching for “File Share”.
If you are a developer, or if you’d like to file a bug or feature request, please check out the project site.
Download it on your phone by scanning this QR code:
