Introduction to Internal Viewer
The aim of the Internal Viewer is to display any file as fast as possible in Text or Hex view mode. It reads only parts of the file which are displayed or used for calculation of vertical scroll limit. It means that you can view 200 GB file with the same speed as 200 KB file (assuming that it will display the same part of both files).
You can use the Internal Viewer to: view a file content as text (the Text view mode) or as hexadecimal values (the Hex view mode); search for text or match regular expressions; copy blocks of text to the clipboard or to disk; convert text to chosen code page; and other tasks.
