ATPad is a simple Notepad replacement but provides many additional features, such as: Tabbed environment - especially useful for working with multiple files (for example, logs). Fully customizable editor - colors, fonts etc. Lines numbering - it's hard to find these days any respectable editor which does not support this feature. Portability - ATPad does not require installation, it can be started from any drive (fixed or flash) and leaves no traces on host computer after finishing. Lots more.....(free).....
