What is a CFB file?
A .CFB file usually stores data in the Compound Binary File format. Microsoft developed this format. It acts like a file system within a single file. It holds multiple streams of data. It is the base for older Microsoft Office formats like .DOC and .XLS. However, a .CFB file can also be a lighting fixture library for CAST Wysiwyg, a forensic data report from Cellebrite, or a 3D print file from Cubicreator.
How to open CFB files?
Because .CFB has multiple possible meanings, viewer.online/cfb analyzes .CFB files to identify their exact format and creator software. It shows which programs can open the file and usually previews it. If the file is a standard Microsoft document, you can often open it using Microsoft Word or free alternatives like LibreOffice.
Software and tools
To open forensic reports, you need the Cellebrite UFED software. Lighting design files require CAST Wysiwyg. Developers can inspect Compound Binary File structures using tools like `oletools` or `Structured Storage Viewer`.
Summary
Because .CFB files use the known DOC format, viewer.online/cfb can safely open and display them online, eliminating compatibility problems.
