Same files stored at multiple locations can consume unnecessary disk space. There is a simple way to find such duplicate files and delete them in Windows.
CCleaner is useful for doing this. Besides deleting junk files, cookies, cache and temporary files, it also can find such duplicate files and delete them.
Here is how :
Open CCleaner and choose Tools > Duplicate Finder.
The search criteria can be modified to either include or exclude system files, hidden files, read only files and files below or certain size.
So for example : to find duplicate files that are more than 100 MB in size but which are not system files or hidden files refine the search parameters. Check these options to be ignored, then choose the drive location.
Also, specific folders can be added in the search criteria by clicking Add. File type can also be specified and also if search should include files and subfolders.
Finally hit Search for the scan to start.
It will display a list of duplicate files.
Choose the version to be deleted and select Delete.
Next, confirm the deletion.
The duplicate files will be removed.
All done.
Happy system tuning.
