What is a GTA file?
A .GTA file usually functions as a Microsoft Groove Tool Archive. Microsoft created this file format for Microsoft Office Groove (later renamed Microsoft SharePoint Workspace) to distribute mini-applications and customize document processing.
Alternatively, a .GTA file can be a Generic Tagged Array. Developers use this format with the libgta library to store multidimensional data arrays and rich metadata. Because the .GTA extension has multiple possible meanings, it can be difficult to know exactly what is inside your specific file.
How to open GTA files?
Opening a .GTA file depends on its actual format. To open a Microsoft Groove Tool Archive, you need legacy software like Microsoft Office Groove 2007 or SharePoint Workspace. However, Microsoft has officially discontinued these programs. If the file is a Generic Tagged Array, you must use command-line tools or custom software that includes the libgta library.
