Advanced HTML Tool kit offers a built-in offline browser. You can explore folders and view html pages with a click - just select the file and it will be shown in the same window! Includes:
The program allows users to replace entire paragraphs of text within the files in the selected folder (and its subfolders). You can also delete and insert paragraphs.
Optimization allows you to compress html files so they will appear in the browser without changes but their size will be reduced. The program doesn't corrupt scripts, works correctly with preformatted text and styles. You can specify different options of optimization.
The program supports projects so you can save your settings (including the root directory for exploring) to different files. Changed files may be copied to the specified directories (e.g. if you wish to optimize your files and publish them in the net but don't wish to change the original files).
