FileCarver is a program for editing binary data files that follow an arbitrary format that you specify. FileCarver offers a completely new approach to binary file editing, when compared to the traditional use of a hex-editor. When using a hex-editor, you are forced to calculate the offset and the format of the data that you want to change, which, at times, can be nearly impossible (depending on the file format). On the other hand, with FileCarver, you simply specify the format of the file prior to opening it, using an XML definition file, and you are automagically presented with a complete graphical user interface to edit the file.

Traditionally, binary file formats have had the disadvantage that they were difficult to edit without custom-made programs that took a lot of man-hours to create. In contrast, textual files such as XML do not require anything more than a text editor to modify, but are burdened with their signficantly increased file size, and much slower loading times (since XML has to be parsed) when compared to binary file equivalents.

With FileCarver, you can have the best of both worlds. Your files will be regular binary files, and thus will take little space and load quickly, while being easy to edit with FileCarver, after defining their formats in XML.
