Notepad++ doesn’t have a built-in file comparison feature like some dedicated diff tools. However, you can leverage plugins to compare files effectively within Notepad++. This article explores how to compare two files using a popular plugin called “Compare.”
Comparing Files with the Compare Plugin
The Compare plugin is a powerful addition to Notepad++ that enables side-by-side file comparison. Here’s how to use it:
-
Install the Compare Plugin: Navigate to “Plugins” -> “Plugins Admin” in the Notepad++ menu. Search for “Compare” in the available plugins list and install it. A restart of Notepad++ might be required.
-
Open the Files to Compare: Open both files you want to compare in Notepad++. You can have them open in separate tabs or split the view vertically or horizontally.
-
Launch the Comparison: Go to “Plugins” -> “Compare” -> “Compare” or use the designated keyboard shortcut (often Alt+D).
-
Review the Differences: The Compare plugin will present a side-by-side view of your files, highlighting any differences in text. Different colors are usually used to indicate added, removed, or modified lines.

Understanding Configuration File Structure
The provided configuration file appears to define settings for communication ports, application parameters, and device mappings. It uses a simple key-value pair format within different sections denoted by bracketed headers (e.g., [PORTS], [SETTINGS]).
Let’s break down the common elements:
-
Sections: Each section groups related settings. For instance, [PORTS] defines connection parameters for various communication methods like Serial, TCP/IP, and UDP. [LOCOS] lists device identifiers and their associated communication details.
-
Key-Value Pairs: Within each section, settings are defined using
key=valuepairs. For example,AUTOSTART=1in the [SETTINGS] section indicates that autostart is enabled. In [PORTS], entries likePORT1=TCP,10.0.4.19,14001,1,0xFF,0,Office Modem #1define connection parameters for PORT1. -
Comments: Lines starting with
//are comments and provide explanations for the settings. These are crucial for understanding the purpose of each configuration parameter.
Key Considerations
While Notepad++ with the Compare plugin provides a convenient way to compare files, remember its limitations for complex comparisons. Dedicated diff tools offer more advanced features like merging changes and visualizing differences in a more comprehensive manner.
Conclusion
Using the Compare plugin in Notepad++ allows for efficient side-by-side file comparison. While not as feature-rich as standalone diff tools, it offers a readily available solution for quickly identifying differences between two files. Understanding the structure of configuration files, with their sections, key-value pairs, and comments, is essential for interpreting and modifying system settings.
