FileGraph - File Analysis Tool With this small tool, it is possible to analyse files and get a visual representation of what kind of data it contains. It is completely up to the user to interpret, from the visual output, what kind of data the file may hold. This tool is definitely not for everyone, but if you sometimes work with unknown file types, this may be a useful help. Analysis The program will analyse the given file in 8-bit chunks, also called a byte. Each chunk has 256 different combinations. The displayed graph has 256 bars along the x axis. Each bar on the graph will represent how often that value occurs in an 8-bit data chunk. Data Density The bottom status bar shows an interesting detail, "Data Density". From this value you can determine how compressed the data is, and also how well it would benefit from packing the file using compressing software. Options - Ignore Zero Normally, the graph autosizes the height of the y axis, depending on which of the 256 bars has the highest occurance. In most types of files, the most occuring index will be zero. By ignoring the zeros, the bars will autosize depending on the highest occuring index that is not zero. You can see the current scale of the y axis by looking at the last field in the status bar. Generated Graphs The main menu has a "Generated" category, which contains some examples of how different types of data can look, when analysed. In a sense, they are completely useless, but will still help you learn how to tell the different kind of data types apart.
