Utility for quick extraction of embedded files from Office Open XML (OOXML) files.

Specifically, it unzips the document, looks through any compound files in the embeddings directory and extracts anything interesting into a series of numbered files. By default it will also attempt to determine the correct file extensions from the content of each file using libmagic.

If you're interested in something other than the files mentioned above, you can try running unzip on the document rather than this utility.

The current version has only been tested by extracting pdf files from PowerPoint presentations and might not handle your specific use case. Bug reports and pull requests are welcome.

Install rust and run

cargo build --release

The resulting executable can be found at target/release/unembedx.

By default, compilation requires file-devel (fedora), libmagic-dev (debian, ubuntu) or equivalent. This allows unembedx to automatically append the correct file extension to the extracted files in some cases.

To build without the file extension logic, you can instead run

cargo build --release --no-default-features

Extract all embedded files into the current directory

./unembedx some-presentation.pptx

Use --help for more information.
