#Picture file deduplicator windows#
Automatically locate duplicate files in Windows Explorer. Protection for system files and folders that will prevent damages to your system files when removing duplicates. Process priority settings that will let the application scan in your computers IDLE time. Has intuitive interface and rich documentation. Support for all kinds of removable media - usb drives, diskettes. Duplicate files can be moved to Recycle Bin, custom folder or deleted permanently. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of Image Deduplicator. Older or smaller files can be automatically marked for deletion. Let’s go through the duplicate photo finder tools one by one to understand them better: 1. Image Deduplicator alternatives are mainly Duplicate File Finders but may also be Duplicate Images Finders or File Search Utilities. Select Text Filters at the top of the Grid view. Internal preview supporting images, videos, music, text and binary files. Go to Photo menu > Stacking > Expand All Stacks to show all of the photos. The duplicate remover has the following features: Find duplicate files or find similar files in user specified folders, hard drives, computers or entire networks. The duplicate remover is a powerful utility for finding duplicate files in a folder and all its sub folders. There is an option to protect system files and folders which is recommended to be turned on. You can also set which folders you want to exclude from the auto mark. The auto mark algorithm has advanced settings to exclude from auto mark files with user specified extensions, file sizes, file dates and file names. After the scan process is finished the program shows you all duplicate files in groups and can automatically mark the older files for deletion. You can also preview the files in binary mode. It uses fast binary comparison algorithm and has internal preview supporting a lot of image, video, music and text file formats. The application will compare the content of your files so it will find duplicates even if they are using different file names. Experimental results show that PXDedup achieves a good reduction ratio when making a backup of a dataset consisting of large amounts of JPEG files, especially when the dataset includes many JPEG images which have few visual differences.Fast Duplicate File Finder will find all duplicate files in a folder and its sub folders. This operation further reduces the data size by making use of the feature that a high quality JPEG image can be recompressed with a bit lower quality parameter without quality loss. Besides, PXDedup recompresses unique image chunks before storing them on disk. The visually identical image chunks are regarded as redundant chunks and are eliminated. Different from traditional deduplication techniques, PXDedup decompresses a JPEG file to an image first, and then partitions the image to chunks. This paper proposes a deduplication method for JPEG files from a new perspective: visual redundancy which is named PXDedup.
However, traditional deduplication techniques based on binary stream are not efficient for JPEG files, for the image compression process breaks redundancy. To reduce the storage cost, data deduplication is proposed and has now become a requisite component of backup systems. Most images are compressed to JPEG format, and the image data accounts for a large part of the data growth. Moreover, existing techniques of mobile phone make image become one of the main ways for information presentation. The explosive growth of data brings a big challenge for the data storage and backup of data centers.
