Methods for Comparing Files
There are several methods you can use to compare files, depending on your specific needs and the tools at your disposal. Here are some of the most common methods:

- Visual comparison: This method allows you to view the differences between files side by side, making it easier to identify changes, especially in large files.
- Diff and merge: This method involves creating a diff file that contains the differences between two files, which can then be used to merge the changes into a single file.
