ASCiiCodes is Xray Vision For Files. It displays the codes that are inside files. ASCiiCodes reveals hidden text inside program files such as hacker messages and copyright notices for actual owners of the program code. ASCiiCodes identifies file types for media files which can help you decide what program to use if Windows can't open it since Windows decides what program to use based only on the file extension.
American Standard Code for Information Interchange (ASCII) is the language of digital devices. ASCiiCodes displays those codes from any file that the user selects.
The codes represent computer programs, digital representations of images, as well as human readable communication. Knowing what codes are in a file can be helpful in determining the contents of a file.
Files consist of bytes of binary data. A byte is 8 bits of data. A nibble is 4 bits of data. A bit is the smallest unit and can be either 1 or 0.
There are 16 possible codes (0-15) in each nibble represented by one of the following hexadecimal numbers: 0123456789ABCDEF. The letter A represents the number 11 through the letter F represents 15. A byte is represented by two nibbles (00-FF) which is defined by an ASCII code.
ASCiiCodes' display is divided into two areas. The display area on the left consists of the text value of the file arranged with 16 characters per row. Characters which do not have a displayable text value in standard fonts (00-1F, 7F-9F, and AD) are displayed with a question mark "?". On the right is the hexadecimal value of each of the text characters. The position of each hexadecimal value is labeled at the top of the display.
