Papa’s Best CFBF Optimizer
A command line tool to optimize and defragment Compound File Binary Format (CFBF) files.
CFBF is the underlying format for Windows setups (
.MSI), Word documents (
.DOC), PowerPoint presentations (
.PPT), Excel sheets (
.XLS), and many more. CFBF Optimizer removes needless sectors and abandoned data from the files and reduces fragmentation in the rest – much like the now-abandoned Document Press.
Runs on Windows 7–10 and on Linux with Wine.

In comparison with Document Press, CFBF Optimizer reaches the same optimization level with small files (CFBF v3) and is superior with large files (CFBF v4). Sizes are in KiB:

|RSS Bandit setup||10 687.5||10 687||10 656||10 687|
