FOCA is an open-source collection of tools designed to help users examine websites for potential issues with their documents. This software supports a variety of file formats such as DOC, ODT, ODS, SVG, and PPT to name a few. By conducting basic metadata analysis on these files FOCA assists in determining if the website contains any corrupted documents or possible issues that need attention. The results are neatly presented making it easy for users to identify and address these concerns promptly.
