Answer 1

Tiddlywiki has several methods of saving data, depending on which browser is used. As you could see in the source.

• If ActiveX is enabled, it uses Scripting.FileSystemObject.
• On Gecko-based browsers, it tries to use UniversalXPConnect.
• If Java is enabled, it uses the TiddlySaver Java applet.
• If Java LiveConnect is enabled, it tries to use Java's file classes.
