Viewing as Hexadecimal
The Hexadecimal tab allows you to view/edit the BLOB data as hexadecimal.
The context menu of the working area provides additional functionality for BLOB Viewer/Editor: use the Save to File... and the Load from File... context menu items to save the hexadecimal data to a file, or load data from a file.
