- Description
- The xlsb file type is a binary file format used to store Excel spreadsheets. It is a compressed version of the xlsx file type and can only be opened in the Microsoft Excel application. Compared to the xlsx, the xlsb format is much smaller in size and is less prone to corruption.
- An AZW3 file is an eBook created in the Kindle Format 8 (KF8), Amazon's successor to the .AZW format. It supports newer features such as HTML5 and CSS3 support as well as many other formatting capabilities. AZW3 files often include DRM protection and are used as the download format for many Amazon eBooks.
