Opening a File with the Hex Editor

Steps

Control-click a file in the project navigator.
Choose Open As > Hex.

View and edit a file in its binary format by opening it in the hex editor.

The hex editor has three areas:

On the left, the line numbers
In the center, the hexadecimal representation of the bytes in the file, 32 bytes per line, one byte per column
On the right, the plain-text (ASCII) representation of those bytes

From the Editor menu, you can hide the line numbers or the plain-text representation. You can also choose to display the byte codes in groups of 2, 4, 8, 16, or 32.
