Overall, a great tool for handling large files. Code formatting is very nice and customizable making it very easy to write scripts or SQL or any other language. It is easy to navigate and it remembers files and keeps them in context when shut down and relaunched. My analysts and programmers all use this editor every day.
As a program UltraEdit comes ready to use out of the box and requires very little setup for it to be extremely useful. It's flexibility among a wide array of tasks and files makes it a go-to for all our troubleshooting and data viewing needs. Timely updates and great support.
When you want to quickly edit a file, TextPad starts up quickly and has many features over Microsoft Notepad. Visual Studio Code is an alternative in that it is full-featured and will edit text files but is slower at startup. I prefer the macro feature in TextPad due to its simplicity.
I have evaluated Notepad++ as an alternative to UltraEdit. In some cases, such as loading time, Notepad++ is a superior product. However, in terms of editing existing macros, and editing very large text files UltraEdit is a much better product.
