The way to get over the problem is to lay out binary numbers into groups of 4-bit, and these groups of four bits employ another form of numbering system which is in general use in computing and digital system: Hexadecimal Numbers. But sometimes it has to work with quite a few 16 or 32 bit binary numbers. For instance, when binary system works with large digital systems like computer, it usually has to contain 16 or even 32 digits, which is difficult to read or write without generating any errors. The major drawback of binary system is that binary string can be quite long compared with its equivalent of decimal base.

The hexadecimal numbering system is commonly used in computer and digital systems in order to reduce strings of binary system to a group of 4 digits which can be easily understood and get away from unnecessary errors. The word 'hexadecimal', hex for short, means sixteen and this kind of number system consists of 16 different digitals: 0-to-9 and A-to-F. Likewise binary, hexadecimal is another numbering system and it is widely used in computing as well. You've no doubt heard of binary in computing which expresses numbers using only two digits 0 and 1. The word 'hex' in comes from 'hexadecimal', a standard numbering system. If you are new to this, you can continue reading to learn about hexadecimal, hex editor and how to use it. Hex editor is mainly used by computer professionals to fulfill various tasks such as data recovery, analyze files, edit data structure, disk clone, edit partition table, etc. If you edit data with hex editor, you are said to hex edit the file and operations using a hex edit is called hex editing. Hex edit is able to edit binary files which contain data in machine-readable form that can't be read by human. Hex editor is computer software used to view and edit raw data contents of a file, while other software tries to interpret data for you. Recover deleted files using data recovery software
