Hi all. I developed a small and friendly file manager for Kindle PaperWhite (it should also work on Touch).
The KindleExplorer is integrated with the editor
LeafPad, and the terminal
Kterm.
Last version can be downloaded from project home:
http://kindle-explorer.googlecode.com
To get started, you need to install
Unified Application Launcher and unpack the archive to "extensions" folder.
I would be happy to hear your feedback.
