DISCO detects certain kinds of hidden content in Microsoft Word, Excel and PowerPoint files. The types of hidden content we identify are “revisions,” “hidden sheets,” “very hidden sheets,” “comments” and “notes.”
We have added an alert and metadata information to indicate which type of hidden content is present on the document you’re reviewing. The presence of hidden content indicates to a reviewer that they should download the original to review the full contents of the document. All databases created after March 26, 2016, will have this feature.
