Find matching folders that have lots of duplicate files. e.g. find large folders that have been copied to multiple locations.
After determining the largest duplicate* files, deClutter disk analyzes the folders to group folders that have more than the configured number of duplicate files (e.g. 8 duplicate files) in common. It should be noted that the folders may have more duplicate files than the number in common with the grouped folders (hence the number of duplicate files displayed may not be the same for all folders with the same duplicate number).
All Partial duplicate folders found are displayed from largest to smallest – to focus on identifying the files that are using the most disk space. Partial duplicate folders are given a “Dup#” (duplicate number) and the Partial duplicate folders are grouped together. The Dup#, folder, total number of duplicates in the folder and total size of the duplicate files in the folders are displayed in a list from largest to smallest.
The list of Partial duplicate folders is sortable on Dup#, Folder name, Num. duplicates and size. This is done by clicking on the column heading you want to sort.
The rows are color coded to highlight Partial duplicate folder groupings and to make it easier to read across a row.
The intended use of this display is to determine folders that are partial copies of other folders and are 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. Like merging the folders into a single folder.
- Deleting files. To do this, select the folder rows, right click to see the popup menu of options. Select “Delete duplicate files from selected folders(s)” to delete all the duplicate files in the folders specified by the rows selected. Note: This will delete all duplicate files in the folders – this may be more than the duplicates that are in common with the folder grouping. A window will display all files to be deleted, and request confirmation before deleting the selected files.
After deleting files using deClutter disk the Largest files, Duplicate folders and Partial duplicate folder lists are refreshed based on the initial scan and analysis, excluding the deleted files. The current tab’s list is updated immediately, while the other tabs are refreshed when changing to that tab.
After deleting files using Windows File Explorer, deClutter disk will not be aware of the file changes until you rescan the disk or folder with the “Start” button. It is suggested this be done from time to time to get the new ‘full picture’.
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 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.
