it does find duplicates efficiently…BUT - how the hell can you tell out of the 2 which one is the one you want to keep?I have migrated files and wanted to clear duplicates, I let the app scan, and it did find the duplicates but all it gives is the folder name and the duplicate file in it (see the last screen shot above)for example...how can you tell which of the 2 folders “NV3DVision” resides in User/downloads/ and which resides in User/Backup ? - really stupid.And what if you want to delete duplicate folders that contain exact files? why only remove single files and not the whole folder?!you get my point… APP DELETED.

I will direct my abuse concerns to Apple directly about this app, but this product’s inclusion in the ‘Free’ category is misleading, deceptive and wrong:MISLEADING NAME: The product is named ‘Cleaner - The Duplicate File’, but the download does not provide any functionality to clean anything or delete any duplicate files. FALSE CLAIMS: The product page on the Mac App Store begins with a description of the ‘free’ Cleaner: three ‘features/value propositions’ are given for a product that as downloaded is 100% incapable of performing any of the following: "Cleaner-The Duplicate File is the most comprehensive duplicate file for your Mac. It quickly scans your hard drive to find all the duplicate files on your Mac. You can then selectively choose which duplicates to delete and free up precious space on your hard drive.”+ This is not the “most comprehensive duplicate file for your Mac”; assuming this is a proofreading error, it also is not the “most comprehensive duplicate file [CLEANER] for your Mac”. It doesn’t even remove duplicates in a sub-comprehensive manner. + This app does not allow users to “selectively choose which duplicates to delete”, and is not capable of “free[-ing] up the precious space on your hard drive”.+ While it does “[scan] your hard drive”, it does not "find all the duplicate files on your Mac” either literally or by inference (that the scan process precedes cleaning of found dupes): this ‘free’ product’s capability is to confirm that you have duplicate files. + If you want to do anything beyond looking at a list of duplicate files (like ‘clean’ them from your drive), Liu Kun has a paid product available to ‘clean’ your drive. Liu Kun’s free product, downloaded here, does not ‘clean’ anything’.NOT FREE: In fact, this ‘free duplicate cleaner’ app is a marketing tool for a different product that is not free but promises to ‘clean' duplicate files once purchased.IN CLOSING:If Apple is serious about its commitment to the App Store’s integrity and retaining user trust in the apps it retails, this product (according to the ‘Apple App Submission Standards’) must be removed from the store and only reconsidered under the following conditions:(A) If this ever is resubmitted as-is for the free app category, it must be renamed to describe a promotional tool (‘Cleaner Infomercial App - Free!’). Optimally, Apple would reject it again and require adding a trial-period demo that cleans duplicate files or an open-ended demo that cleans a limited number of dupes. While limited, it would no longer be deceptive and entirely misrepresented as it is now. (B) On any free app product page, the descriptive text must be changed so the features deceptively associated with the free app are clearly labelled as ‘UPGRADE TO PRO to unlock these features’. The marketing text must clearly state what this app actually does; in the case of this product category, the reasonable expectation of a ‘Productivity’ app is to do something productive. Were this a Utility named “Create List of Duplicate Files”, there would be less need to protect consumers from downloading based on reasonable assumptions.—————————————————————DON’T KILL THE MESSENGER!—————————————————————The submissions standards Apple requires app developers to follow is exhaustive, exacting, at times arbitrary but ultimately a process that ensures quality standards and generally keeps the riff-raff or evildoers from wreaking havoc on our Apple devices. The stated rationale (paraphrased here) by Apple is ‘these standards are critical in making App Store/iTunes Store a marketplace that consumers trust, where apps can be downloaded and run safely, and protects users and their devices…’ Apple’s intent behind all these rules and limits is clear: it is good for business and users of Apple devices. The consequences of purchasing apps that involve misrepresentation, malicious behavior or degrade system performance are serious, and just one poorly built utility can drag an entire system’s performance into the gutter. I totally agree with this, and in critiquing this app I am also signaling to Apple that as they hold developers to the highest standards, we in the marketplace hold Apple to equally rigorous expectations: this is an example of Apple failing within an overwhelmingly successful product.
