File Difference for Mac

Overview of the comparison utility

A compact tool that instantly exposes differences between files and directories, saving developers from manual, time-consuming inspections. It presents changes clearly so you can spot code or text alterations at a glance.

Best use cases

• Comparing successive project releases or branches in real time.
• Quickly locating specific modifications without scanning entire files.
• Excluding irrelevant files from comparisons to reduce noise.

Supported file formats

This utility handles most standard file types, including:

• HTML
• CSS
• TXT
• JSP
• CCP (and additional common formats)

How changes are displayed

• Differences are shown line-by-line with multiple colors to indicate added, removed, or modified lines.
• Intraline differences are highlighted so you can see edits inside a single line of text.
• A rapid search/navigation feature lets you jump to any specific line within seconds.

Directory comparison and filtering

• Folder comparisons include all nested subfolders automatically, so entire projects can be compared in one pass.
• Expression-based filters let you exclude files or patterns that aren’t relevant to the comparison, focusing results on what matters.
