Which text-editing tool is commonly used to modify configuration files for data connections?

• A. RStudio
• B. SSMS
• C. Notepad++
• D. Toad

Answer: (C)

Editing configuration files for data connections involves working with plain-text files that contain settings like host, port, database, and credentials. Notepad++ is a lightweight Windows text editor designed exactly for this kind of task. It handles plain text well, supports multiple file formats such as INI, JSON, YAML, and XML, and offers useful features like tabbed editing, robust search and replace, and syntax highlighting to help you spot mistakes quickly. This makes it easy to edit connection strings and related config settings without the overhead of a full development environment.

Other tools in the list are more specialized for their respective domains: RStudio is an IDE for R programming, SSMS (SQL Server Management Studio) is focused on managing SQL Server databases, and Toad is a database administration tool for various databases. While they can edit text, they aren’t the go-to choice for quick, flexible configuration edits, which is why Notepad++ is commonly used for this purpose.
