After opening the files there are some alphanumeric, special characters. I am unaware of these files and their appropriate functions.

    A hex editor is a small type of computer program that allows user to change the machine language which makes up the files that the computer understands. Hex editor that are designed in such a way that they can read and edit sectors of hard disk and floppy drive. User can install hex editor to read, write and extract some contents of a file. Many of the hex editors show the data from a file in the hexadecimal format thus they are represented as 4 groups of 4 bytes.

    You can access the main memory of RAM using the HxD editor. HxD editor can edit and modify the files of main memory without having any limitation of the file size. It has a very easy user interface which helps us to search, replace, export, checksum, insertion of byte, file shredder, concatenation and much more. The drive and memory are represented in the same way as files. Thus drives and memory can be edited in the same way as files edited with an undo function so that they can be returned back to the previous stage. HxD is freely available and is very easy to install. HxD can export data to several other format such as plain text, html etc.

    Suppose that you have opened an executable file in the hex editor you are having installed on you system. The code in the executable file is compiled and you don’t get the plain text as output. After the compilation you will get a code which is represented in a low level language which only the machine can understand. So after the compilation of code of the executable you can access the physical storage media such as USB, hard disk, floppy disk etc. depending upon which type of editor you are using.
