You might occasionally discover identical (or seemingly identical) files on your computer. This usually happens if you save copies of the same file in different locations on your computer. Identical files waste storage space and can make it difficult to manage your files, since it's more difficult to find the version you want when several files have the same name.
Open Search by pressing Windows logo key
In the Search box, type the name of the file that you suspect might be duplicated.
On the toolbar, click Views, and then click Details.
Scroll down the list, looking for files with matching file names and file extensions. When you find one or more files that match, compare their dates in the Date Modified column. If their dates are the same, the files are probably duplicates. You might want to open the files and compare their contents to be certain.
Click the file you want to delete, and then press DELETE.
If your computer has many duplicate files, you might want to use a program designed to find and remove duplicate files.
