SweetScape 010 Editor is a professional-grade text editor and hex editor designed to quickly and easily edit any file or drive on your computer. Combining an easy-to-use interface with a whole range of editing tools, 010 Editor is a valuable tool for anyone working with text or binary files. One of the most powerful features of 010 Editor is the ability to parse virtually any binary file using a Binary Template. Instead of browsing through a long range of hex bytes as with traditional hex editors, Binary Templates allow a file to be understood. Templates are easy to write and can be used to completely parse any data format, such as BMP or ZIP files (Templates for reading these files are included with 010 Editor).
