Quickly and easily compare all files in Git (a commit or Staged/Unstaged files) or TFS (a changeset, shelveset, or files with pending changes) to see what has changed. Instead of clicking on each file individually and choosing to compare it with a different version, just click one button to compare all of the files.

You may edit the extension's settings from the Tools -> Options... -> Diff All Files settings page.

Visit the Diff All Files project homepage for more information or to make a feature request or bug report.

This extension is also available for Visual Studio 2022, Visual Studio 2019, 2017, 2015, 2013, and 2012.

NOTE: While some extension installers may indicate they support multiple versions of Visual Studio, that is not the case. Please ensure you install the correct extension version for your version of Visual Studio.

Features

• Compare files one at a time, many files at a time, or with all files combined in a single file.
• Uses the same diff (i.e. compare) tool that you have configured in Visual Studio. e.g. KDiff, Beyond Compare, Visual Studio, etc.
• Exclude comparing files with specific extensions, or files that have been added or deleted from source control.
• Button to quickly close all diff tool windows that have been opened.
• Specify the file versions to compare against (i.e. Unmodified, Workspace, Previous, Latest).
• Supports TFVC source control providers. Git support is no longer available.

Git Support

Please go up-vote this feature request to have Microsoft add Git extensibility points to new versions of Visual Studio to allow this extension to work with Git again.
