TIImageTool is a program that offers many features of other file managers, taking disk images as input. Since version 1.0 TIImageTool can work with hard disk images using the MESS-specific CHD format.

Java security concerns
In recent times, people start to get suspicious about Java and call it a "security thread". These concerns only apply to Java applets (which are executed inside a browser window). TIImageTool is not run from a browser, it is locally installed. Like every locally installed application, it runs with all privileges of the user who started it.
However, when you install a Java Runtime Environment you should make sure that Java support in your browser is not unexpectedly turned on. Start your browser (Firefox, IE, whatever) and make sure that the "Java support" in the browser extensions/plugins is deactivated.
