4.2 Incorrect Highlighting

Check Settings:
- Go to Plugins > Compare > Settings and review the settings.
- Ensure that the “Ignore Spaces” and “Ignore Case” options are set correctly for your comparison needs.
- Adjust the color settings to make the highlighting more visible.
File Encoding:
- Ensure that both files being compared have the same encoding (e.g., UTF-8).
- In Notepad++, go to Encoding and select the appropriate encoding for each file.
- If the encodings are different, the comparison may produce incorrect results.
Line Endings:
- Different line endings (e.g., Windows CRLF vs. Unix LF) can affect the comparison.
- In Notepad++, go to Edit > EOL Conversion and select the appropriate line ending for each file.
- Converting both files to the same line ending can resolve highlighting issues.
Large Files:
- Comparing very large files can sometimes lead to performance issues and incorrect highlighting.
- Try comparing smaller sections of the files or use a more robust comparison tool for large files.

4.3 Plugin Crashing Notepad++

Update Plugin:
