Sweetscape is celebrating the 10th anniversary of 010 Editor
by giving a 25% discount on new purchases and upgrades through the month of September.
This makes a single user license $97.46 for commercial purposes and $37.46 for home/academic use.
010 editor is not likely to replace your favorite text editor for programming (I continue to use Kedit and EditPad Pro for that), but the latest version is more than adequate as a text editor. What sets it apart is that it can edit just about anything on one's computer, including binary files, disk sectors and even in-memory processes. It works well with, and converts between, many data types, and allows users to create templates to handle any it does not know.
It integrates nicely into the Explorer context menu and is very fast, even with huge files, which is why it has become my go to editor for most ad-hoc file viewing and editing. Although I have only used it on Windows, it also runs on Mac OS-X and Linux (Ubuntu 10.4+).
