File duplicates can take up valuable disk space. While that's usually not an issue on a 2 or 3 Terabyte hard drive, it can be one for Solid State Drives and other hard drives that usually offer lower storage capacities.
Dup Scout, available as a free limited version and a professional version, is a powerful program to locate duplicate files on the system. The free version is limited to scanning 500,000 files and a maximum storage capacity of 2 Terabytes. This should be sufficient for most uses.
You can start a check for duplicate files with a click on the duplicates button in the main interface. The program can search for duplicates in a selected folder, on all hard drives, on servers and NAS devices, or all servers on a network.
You may want to click on options before starting the search to configure search parameters. Here you can change performance related options or exclude directories from the scan. The free version lists options only available to users who have purchased the pro version of the software. This includes actions that are run automatically on duplicate files (for instance deleting the oldest files, or replacing the newest files with links pointing to the original copy of the file).
The process speeds depends largely on the hard drive the files are stored on and the processor of the system. Processing time is usually very fast though.
All duplicate files are displayed in list form in the interface. The program indicates the original file name, the total number of files (2 or more), the individual file size and the total space wasted by the duplicates.
A click on a row opens the the duplicate file set in a new window. All file paths, creation and last modification dates are displayed here. This is also the place to select an action that you would like to perform. Available for selection are to delete the duplicate files, replace them with links, move them to a directory, compress the duplicates or to compress and move them.
You can alternative highlight some or all rows at once and pick an action from the actions button at the top of the interface.
Dup Scout displays statistics below the duplicate file listing and with a click on charts in the toolbar.
The chart image can be copied to the clipboard or printed. Duplicate files can not only be sorted by file extension, but also by file size, access time or user name.
A click on Preview opens a preview window where all actions are displayed. The program lists the total number of duplicates and the space that you save when all actions are performed. Checkboxes are available to block a duplicate from being processed. Once you have made that final selection you can press the execute button to start the process.
Users can create duplicate file reports which can be saved as HTML reports by free users. The commercial version adds XML, SQL and other exporting options.
Dup Scout is a fast duplicate file finder for all recent versions of the Windows operating system. Free users, at least at the beginning, may be irritated by the presence of pro only features.
Windows users can download the latest version from the developer website.
