High Quality Content by WIKIPEDIA articles! Microsoft Office Document Scanning (MODS) is a scanning and OCR application included with Microsoft Office introduced first in Office XP. The OCR engine is based upon Nuance's OmniPage. Microsoft Office Document Scanning is suited for creating archival copies of documents. Microsoft Office Document Scanning is closely tied with Microsoft Office Document Imaging, the application that manipulates MDI (Microsoft Document Image) files. The application can also create TIFF files. Notably, this application can also embed OCR data into both MDI and TIFF files. This enables some sort of automated text searchability on the files, which is integrated into the Windows shell Search function.
