Welcome!

Welcome to DeltaWalker Classic—Deltopia’s multi-platform application for visual file and folder comparison.

We hope you find it both useful and fun.

This help, like DeltaWalker Classic itself, aims to be simple, useful, and intuitive. It introduces you to comparing, editing, and merging many types of files, as well as comparing and synchronizing folders.

Even if this is your first time with DeltaWalker Classic, chances are you’ve already visited www.deltawalker.com. If not, do check it out for an overview of what DeltaWalker Classic can do.

Whether you are a beginner or a pro, be sure to leaf through the How Do I? section: its short, task-focused answers will likely cover what you want to know.

The task-oriented Comparing Files and Comparing Folders sections support you as you perform these two key activities.

DeltaWalker Classic adapts to the way you work: it remembers the layout you leave it in, and its Settings window lets you tune everything from the comparison algorithms to fonts, colors, and shortcut keys.

Scripting DeltaWalker Classic gives you both the high-level overview and the low-level detail you need to automate DeltaWalker Classic with scripts. Scripting is not available in DeltaWalker Classic Free.

For a complete reference of DeltaWalker Classic’s dialog windows, see Dialogs.

Turn to Everything Else for anything you didn’t find elsewhere, including working with the comparison history, printing a comparison, and support and contact information.

DeltaWalker Classic runs on macOS, Windows, and Linux. This help uses macOS key names, and its screenshots are taken on macOS. On Windows and Linux, press Ctrl where the help says Cmd, and Alt where it says Option. A shortcut that uses Ctrl on macOS uses Ctrl on Windows and Linux too. Shift is the same everywhere.

Enjoy!
