Duplicate Finder functions as a wizard, guiding you step-by-step through the program. The following is a basic overview of how to find duplicate files. There is extensive context sensitive help in the application to provide you with additional information.
To find duplicate files:
In the Select Search Type dialog box, add files or folders to search.
Define your search type by doing one of the following:
To restrict the search amongst the files and folders in the first list, select Find duplicates within this list of files.
To have Duplicate Finder search between the first list and another list, select Find duplicates between these files and another list.
Click Next.
If you selected Find duplicates between these files and another list in Step #2, the Second File List dialog box appears; add files or folders to create the second list and click Next.
In the Search Parameters dialog box, select the desired options.
Click Next. If no duplicates are found, you are prompted. If duplicates are found, the Search Results dialog box opens; see Deleting and Renaming Files for more information.
Note:
Identical images saved as different formats (i.e. different extensions, such as JPEG, BMP, GIF), are not recognized as duplicates.
If you have a JPEG and save a copy of it, the image is recompressed. Therefore the original JPEG and the copy are a different file internally and they are not recognized as duplicates.
