Word Versioning 1.0 was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The actual developer of the software is etis GmbH. We recommend checking the downloaded files with any free antivirus. The software lies within Office Tools, more precisely Document management.
From the developer:
Word Versioning is a Microsoft Word add-in that brings version control to documents that cannot be stored on OneDrive or SharePoint.
Every version you save is stored inside the .docx file itself, together with a name, the user who saved it and a timestamp.
You may want to check out more software, such as Word File Content Recovery, Atomic Word Password Recovery or Word Password Recovery Standard, which might be similar to Word Versioning.
