What is a .ag file?

The .ag file extension is primarily associated with Adobe Acrobat, specifically for grouping together related PDF documents. These files act as containers or indexes, allowing users to manage and navigate multiple PDFs as a single unit. This is particularly useful for large projects or collections of documents that need to be accessed in a specific order. While not a document format itself, it facilitates the organization and access of PDF content. It helps streamline workflows by bundling related files, making them easier to share and manage.
