FileMerge: Free File & Folder Comparison Tool

Compare files and folders visually, see differences, and merge changes selectively for programmers, writers, and document revision users

What is FileMerge?

FileMerge is a free file and folder comparison utility that comes included with Apple's Xcode developer tools for macOS. It provides a graphical interface for visually comparing two files or folders, and allows you to easily see differences between them line-by-line or side-by-side.

Some key features of FileMerge include:

  • Comparing text files like code, Markdown, JSON, XML, and more
  • Comparing binary files like images, PDFs, and Office documents
  • Two-way and three-way comparisons of files and folders
  • Side-by-side and in-line difference views
  • Selective merging of differences
  • Support for ignoring whitespace, case sensitivity, and more

FileMerge is very useful for programmers working in teams, as it facilitates comparing changes in source code files and merging them. Writers can use it to compare draft revisions of documents. It's also helpful for anyone wanting to visually see differences between file versions or folder structures before deciding what to keep or discard.

As FileMerge comes included free with Xcode, it is widely used by Mac developers and power users. It provides an intuitive way to visually work with file and folder differences right from the comfort of the macOS desktop.
