How do I get CCleaner to find and delete duplicate jpg files?
If you Add an 'Include' you can specify what filetypes to find.
Remember to untick any other Includes (C:\*.*, etc) before searching.
eg. This would add an include to find duplicate JPGs and JPEGs anywhere on the C: drive
CCleaner will not automatically delete duplicate files, it has no way of knowing which ones of duplicate files that you want to keep and which you may want to delete.
CCleaner can find the duplicates, but only you can decide which to keep or not.
