After collecting the file information, deClutter disk analyzes the files to determine duplicates*. Files are considered to be duplicates if they are exactly the same size and the configured file comparison method matches files. All duplicate files found are displayed from largest to smallest – to focus on identifying the files that are using the most disk space. Files are given a “Dup#” (duplicate number) and the duplicate files are grouped together. The Dup#, file name, folder and file size are displayed in a list from largest to smallest.
The list of Duplicate files is sortable on Dup#, File name, Folder name and file size. This is done by clicking on the column heading you want to sort.
The rows are color coded to highlight duplicate file grouping and to make it easier to read across a row.
The intended use from this display is to determine the duplicate files using the most disk space. Actions include:
- Double clicking on a row will open that files folder in Windows File Explorer and allow you to investigate.
- Deleting files. To do this, select the file rows, right click to see the popup menu of options. Select “Delete selected file(s)” to delete all the files in the rows selected. A window will display all files to be deleted, and request confirmation before deleting the selected files.
Note: Normal precautions should be taken when deleting files. It needs to be understood that duplicate files have been matched based on the configured criteria and are most likely identical files, but technically speaking a byte for byte comparison has not been performed (as such a tool would be unusably slow for a normal user). Use a common sense approach.
