Duplicate Cleaner's straightforward interface makes it a snap to start searching for duplicates. You can narrow your search by the type of file, sizes, dates and more. You can specify which drives and folders to look in, and you even get an option to search inside Zip archives.

You're not on your own when selecting which duplicate files to remove. The Selection Assistant lets you select files by groups, dates, drives, folders and more. You can select a favourite folder, and remove files that duplicate it elsewhere, or maybe select the smallest images, or the lowest quality mp3. Power and flexibility is the key!

Lists of files are all very well, but what if you've just made a copy of a directory? Duplicate Cleaner will show you that in the Duplicate Folder browser. Quickly see duplicated directory trees, and easily mark the ones you don't want to keep.

You can specify an input folder to only scan against other folders - and not against itself. This means you can compare 'clean' areas (e.g. archives, cd's) against other areas without generating unneeded lists of duplicate files.
You can also save scans and recall different settings for different jobs at the click of a button.

Duplicate Cleaner offers the flexibility to do what you choose with your duplicates: You can delete (Recycle bin optional), move or copy or rename them. Advanced users may also be interested in the linking functionality offered - you can generate shortcuts and symbolic links. Of course several safeguards are offered to make sure that important system files and programs aren't deleted.

Duplicate Cleaner gives you the power to clean up your image library. Using an advanced visual comparison technique, you can find images that have been rotated, flipped, retouched, resized or saved in a different format. You control how exact or loose you want the comparison to be. You can also match images by the time taken, which is usually embedded in the picture file. This allows for matching of heavily edited images.

The special built-in image browser allows you to view the pictures in the duplicate group side-by-side, for comparison. This will aid in deciding what to keep. You can also display image and camera tags such as size, date taken, and colour depth.

Image comparison is fast, but to really speed up repeated scanning Duplicate Cleaner will store 'fingerprints' of your images. This way if you scan an image archive again, or scan it against a new folder, the cached fingerprint will be used. This will speed things up by over 90%.

Photographers will be pleased to note that Duplicate Cleaner Pro supports all popular Camera RAW image formats.

You can scan and compare audio files using Duplicate Cleaner. Supported formats include MP3, OGG, WMA, M4A, M4P (iTunes), AAC, FLAC and WAV. Cleverly, Duplicate Cleaner can compare audio files by 'listening' to them: looking for similar audio. It can also ompare same or similar music tags across formats by Artist, Title and Album.

Duplicate Cleaner will list details of any audio it finds, including length, bit rate and sample rate in addition to the usual tags. The Selection Assistant can help you pick which files to remove - for instance the shortest version or lowest quality.

Duplicate Cleaner can compare duplicate and similar video files. Support formats include MOV, AVI, MP4, MPG, WMV, FLV, 3PG, ASF, 3G2, WEBM, MKV, VOB, M4V, MTS AND SEC.

You can compare by video content (thumbnail,selected frames within the file or exact hash), audio soundtrack (exact or similar) or metadata.
