QB files are generally categorized by what they do and how they function.

Are you working with Windows or Mac? QuickBooks 2016 or 2019? To get started, it’s best to understand the most common file extensions and what they represent.

For example, your main company files (QBW) are in a whole other realm than the backup data files (QBB).įile formats also differ depending on your operating system and the version of QuickBooks being used. QuickBooks Desktop uses different file types to express varying forms of information. As the QuickBooks online enterprise expands, it makes sense that they need to grow their library of file extensions to accommodate the big data.
