Use an audit workflow to estimate the approximate number of pages in your repositories and to get a report on the number of duplicates using FineReader Server.
Create an audit workflow in the Administration Console. Here you can specify the path to your documents. Remember to select the box "Search for duplicated files", then click OK.
The workflow will crawl through all the files in the library. The interface will show library statistics, providing an approximate number of pages that require conversion. Information about duplicate files will be available in the report.
