The 6.2.4 version of DirEqual for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This Mac application was originally produced by Naarak-Studio. The software is included in System Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
DirEqual is an advanced directory compare utility for Mac. It allows detecting the tiniest changes between folders and display the result with a clear and intuitive way. The differences are highlighted using colors and icons indicating the difference type (size, date or item content).
You may want to check out more software for Mac, such as CopyPath, TrimTheFat or DataLore, which might be similar to DirEqual.
