Category:Sparse executables

This category lists all executable formats that can have data hidden somewhere inside them, without affecting use of the program. Often this is because the format stores both a file size and an offset for some data, rather than just one or the other, which allows data to be hidden between fields. But there are also other places data can be hidden, such as in the code itself preceded by an instruction to 'jump' over the data, or appended to the end of the file, depending on the format.
