DeltaWalker is an advanced, yet approachable and fun to use file and folder comparison and synchronization application/diff tool for Mac OS X that lets you compare and synchronize folders as well as compare, edit and merge files. Most any type of files.



Tens of thousands of users—from savvy individuals to software professionals demanding the very best of their tools, from one-man shops to Fortune 50 companies—trust DeltaWalker with their file and folder comparison needs. Daily. Here's how and why:

  • Software and Web developers—compare, analyze, and merge different versions of source files. Use three-way comparison to compare your changes and those of another contributor with a common ancestor and to automatically merge all non-conflicting differences in seconds. Compare and synchronize a local copy of a web site with its server using FTP, SFTP, FTPS or WebDAV. Compare and syncrhonize with the Cloud – Google Drive and Dropbox. View and compare XML files both as is and canonicalized. Compare and merge HTML files as text then preview in-place with the built-in browser. Visualize and compare JAR, EAR, ZIP and other compressed files as if they were simply folders.
  • Photographers & Videographers—compare your archives and backups using different comparison methods including ultra-fast and 100% reliable byte-by-byte comparison. Rest assured knowing that even your resource forks are going to be compared and copied. Visualize and compare your images. Create HTML comparison reports for future reference.
  • Code reviewers—rely on accurate inline difference visualization to see and understand every change. Stay in context and in control within side-by-side integrated folder and file comparison. Generate HTML reports for archiving and auditing purposes, or for exchange via email.
  • Release engineers and managers—visualize, navigate, analyze, edit, and merge complex changes in folder hierarchies and individual files. Reconcile changes from two contributors using three-way comparison and automatic merging.
  • Language translators—compare two folders with files in different languages and work your way through individual files simply by double-clicking them.
  • Legal and publishing professionals—let down-to-the-letter comparison accuracy show you even punctuation mark differences when comparing different document drafts. Trust DeltaWalker to quickly extract and compare the text of even the largest PDF, Office, and RTF documents.
  • Scientists, researchers, and engineers—save time, eliminate guessing, and minimize errors when comparing text outputs and results of different experiments.
  • Computer users—eliminate information duplication with speed and confidence. Quickly compare entire drives and folders checking only file sizes and timestamps or use byte-by-byte comparison to guarantee that files are same or different, then synchronize with a few simple clicks.

    What differentiates Oro from Pro ?

  2. emanneercs Says:

    Does either Oro or Pro work on .DMG files?

  3. DeltaWalker Says:

    hi emanneercs,
    I believe we answered these questions in our email exchange, but for the benefit of others:
    Oro offers the same advanced functionality as Pro, but on all 3 supported platforms.
    DeltaWalker currently cannot compare DMG files the way it’d compare ZIP files for instance – as hierarchical structures – but it can compare them as binary files using byte-by-byte comparison.
