DocuWorks is document-handling software from Fujifilm Business Innovation, which operated as Fuji Xerox until April 2021. It brings scanned paper documents, Office files and PDFs together in one environment, with functions for viewing, editing, organising, searching, scanning with OCR, printing and sending documents, and for digital signatures. According to Fujifilm's support pages, it is mainly installed on PCs as licensed software, with related services such as DocuWorks Cloud Connect and DocuWorks Trays. DocuWorks 10 is the current generation.
Fujifilm Business Innovation is headquartered in Tokyo, Japan, and belongs to the Fujifilm Group under FUJIFILM Holdings Corporation. The vendor therefore sits outside European jurisdiction. The software is not open source. Because the core runs locally on your own PC, documents are processed there. The vendor's pages do not describe where the connected cloud services host data, so check this before you process sensitive documents through those services.
