WhatsDiff – Compare Files, Folders & Find Duplicates
WhatsDiff is a powerful Mac app for comparing files and folders, analyzing differences, and finding duplicate files. Whether you need to compare documents, photos, videos, audio files, or entire folders, WhatsDiff makes it easy to identify what has changed and manage the results.
Three Powerful Tools in One App
#####1. Compare Files#####
Compare two files and quickly identify their differences. WhatsDiff supports a wide range of file types, including:
----Documents and text files
----PDFs
----Photos and images
----Videos
----Audio and music files
----Other media and general file types
File comparison goes beyond basic file size or modification date. WhatsDiff can compare file content and media metadata, helping you identify differences that may not be visible from the files themselves.
For supported document files, you can compare content line by line and clearly see:
----Added content
----Removed content
----Modified content
----Unchanged content
For PDF files, WhatsDiff supports page-by-page comparison, making it easier to identify differences between two versions of a PDF document.
You can also copy, merge, and export comparison results for further editing, sharing, or archiving.
#####2. Compare Folders#####
Compare two or more folders, including their subfolders and files, and quickly understand how their contents differ.
WhatsDiff analyzes the folder structure and compares files inside the folders. Results clearly show:
----Different – Files exist in both folders but have different content or metadata
----Same – Matching files with the same content
----Left Only – Files found only in the left folder
----Right Only – Files found only in the right folder
This makes it useful for comparing backups, project folders, copied files, external drives, and different versions of your data.
You can copy files, merge folder contents, and export comparison results to help synchronize or organize your data.
#####3. Duplicate Finder#####
Find and remove duplicate files from one or more folders.
WhatsDiff scans selected folders and identifies duplicate files, helping you recover wasted storage space and keep your Mac organized.
You can:
----Scan one or more folders
----Find duplicate files
----Preview and compare duplicate files
----Select duplicates to remove
----Delete unwanted duplicate files
Compare Smarter, Manage Files Easier
