Araxis Merge: The Complete Guide to File Comparison and Merging

What Araxis Merge is

Araxis Merge is a professional two‑ and three‑way file comparison (diff), merging, and folder synchronization tool for Windows and macOS, designed for source code, documents, images, and binary files.

Key features

• Two‑way and three‑way text comparison & merging: side‑by‑side, color‑coded diffs; three‑way merging and automatic merge (Professional edition).
• In‑place editor with unlimited undo: edit directly while comparisons update dynamically.
• Intra‑line highlights & linking lines: shows precise changes within lines and maps corresponding blocks between panes.
• Folder comparisons & synchronization: compare folder hierarchies, sync/merge directories, three‑way folder comparisons (Professional).
• Support for common document formats: extract and compare text from Word, Excel, PDF, OpenDocument, RTF.
• Image and binary comparison: pixel‑level image diffs and byte‑level binary comparisons.
• SCM integration: plugins for Git, Mercurial, Subversion (open repository revisions, compare branches).
• Automation & CLI/API: command‑line interface, Automation API (Windows), AppleScript (macOS) for workflow integration.
• Reports & printing: generate HTML, XML, slideshow or diff reports; printable comparisons.
• High‑resolution UI & large file support: 64‑bit app, Retina/high‑DPI support, handles very large files.

Editions and differences

• Standard: full two‑way compare/merge, folder sync, document formats, SCM access, reports, CLI.
• Professional: adds three‑way file/folder comparisons, automatic merging, and advanced merge workflows.

Typical workflows

1. Two‑way compare: open two files → review color‑coded diffs → click merge buttons or edit in place → save merged file.
2. Three‑way merge (Professional): open base/left/right → automatic merge of non‑conflicting changes → resolve conflicts with point‑and‑click merging and in‑place edits.
3. Folder sync: compare folders/branches → review differing files → perform selective sync or bulk synchronization → generate report.

Tips for effective use

• Use three‑way merges for branch integration to reduce conflicts.
• Configure ignore rules (whitespace, regex) to hide unimportant differences (timestamps, generated IDs).
• Create HTML slideshow reports for shareable change reviews.
• Integrate with Git/Mercurial via file‑system plugins or call Merge from your SCM tools.
• Use the Automation API or CLI to include Merge in CI or custom scripts.

Where to get it and docs

Download, try, or buy from the Araxis website; comprehensive online documentation covers installation, feature details, CLI reference, and integration guides (Windows and macOS).
