Duplicate File Detective is a Windows application that assists you in locating and managing duplicate files on your computer, along with external drives and even network drives. Rather than manually searching to find copies, it quickly scans your system and presents you with what is duplicated so you can decide what to keep. You can always delete, move or compress additional files and even replace them with links so that nothing of great significance is lost.
In addition to the space-saving functionality, the software also assists in ensuring the organization and ease of management of your files. You can also accelerate the process of backing up files, enhance the speed of the search process, and reduce the amount of clutter in the shared folders by eliminating duplicates. This is particularly practical with businesses or anybody dealing with such large volumes of data and desires a more organized, efficient system.
Duplicate File Detective has been evolving over several years and is developed to be able to manage a small and a large environment. Its high power and ability to work with any tool lets you have total control over how duplicates are identified and managed whether you are working on a personal computer or on a company network.
