- Replace file1.txt and file2.txt with the actual file names.
- Press Enter. TextPad will open and compare the specified files.

4.3. Understanding The Comparison Results

After initiating the comparison, TextPad displays the differences between the files.

Color-Coded Differences:
- TextPad uses color-coding to highlight the differences. By default:
  - Red: Indicates lines present in the first file but not in the second.
  - Green: Indicates lines present in the second file but not in the first.
  - Blue: Indicates lines that have been modified.
Navigating The Differences:

5.2. Command-Line Comparison

TextPad can be used from the command line to automate file comparisons.

Syntax:
- Open the Command Prompt or PowerShell.
- Type the following command: textpad /compare file1.txt file2.txt.
- Replace file1.txt and file2.txt with the actual file names.
Automation:
