Beyond Compare provides comprehensive comparison capabilities for both individual files and directory structures. The software supports: Side-by-side comparison with synchronized scrolling Three-way merge for resolving conflicts between versions Inline difference highlighting at the character level Directory tree comparison with recursive scanning Binary file comparison using hexadecimal views
Specialized Comparison Modes
The application includes dedicated comparison viewers for specific file types: Text comparison: Source code files with syntax highlighting for numerous programming languages Table comparison: CSV, database tables, and spreadsheet data Image comparison: Side-by-side or overlaid image viewing with pixel-level differences Hex comparison: Binary file analysis with byte-level granularity Registry comparison: Windows Registry key and value comparison Version comparison: MP3, PDF, and other structured file formats
Synchronization and File Operations
Beyond Compare extends beyond comparison to provide file synchronization capabilities: Bidirectional folder synchronization with conflict resolution Mirror synchronization for backup workflows Customizable file copy and move operations Batch file operations with preview Automated synchronization profiles
A key feature of Beyond Compare is its customizable comparison rule system. The program includes predefined rule sets for common file types such as C++ source code, XML, and HTML files.Mitchell, Scott (November 2006). "Toolbox: Synchronize Files, Rich Textboxes, and More". MSDN Magazine. Retrieved 2009-10-20. Users can configure: Importance-based difference highlighting (critical, important, minor, unimportant) Text handling rules (whitespace, case sensitivity, encoding) File filters by name, size, date, or custom criteria Exclusion patterns for irrelevant files or directories

Reception
Beyond Compare has received generally positive reviews from technology publications and users, though some reviewers have noted a learning curve for new users.
In an April 2009 review, Beyond Compare received four out of five rating stars from CNET. The reviewers initially found the user interface to be "a little overwhelming", but they "quickly got the hang of it" after using the program for a while. "CNET editors' review". CNET. 2009-04-30. Retrieved 2009-10-20.
PC World writer Michael Desmond included the program in a 2005 list of utilities for a "Trouble-Free PC" and praised its "watch list" feature, which monitors folders for changes.Desmond, Michael (2005-05-03).
