Digital document library created by Paperless, an application used to scan and organize electronic copies of documents; contains a collection of documents that have been scanned from paper copies; also stores metadata that has been captured with Mariner's optical character recognition (OCR) technology.

DWLIBRARY files are used for storing digital records of paper-based personal documents. Documents within DWLIBRARY files can be sorted and searched using the data recorded by the software's OCR technology. Users can also enter custom data for searching, such as categories and descriptions. NOTE: Paperless also stores digital receipt libraries in .RWLIBRARY files.
