Do your hard disks have a lot of identical files? They are not the backup files of your but the useless duplicate files that you created or downloaded unconsciously. These identical files will waste our space of hard drives and make our computer slow and slower. Find and delete these identical files on our hard disks by hand is very difficult and impotent. How should we do? Do not worry about it! Here I commend you a powerful and easy-to-use utility that can find identical files automatically and quickly. That is DoubleKiller which is published by Big Bang enterprises. Do you have the same need as me? Give it a try and you will like it. Trust me, no wrong!

There is a good chance that we have more than one copy of many files on our hard drive. And unless we intend the duplication, we are wasting space. DoubleKiller is a free program that can deal with this problem, searching for and alerting us to any files that are in more then one location. DoubleKiller searches our hard disk (or selected folders) for identical files and offers us to delete or move them. It can compare the file using simple date and file size methods as well as a CRC checksum calculation to make 100% sure that the files are indeed identical. We then get a list of all duplicate files that were found and can decide which files should be deleted or not. Important files like dlls, and other system files can be completely excluded from the search using a user defined mask. The program does not just look at filenames; it compares the filename, size and does a quick scan of the files to find the real duplicates. And once we have found them, we can either delete the files or move them to another location, freeing up the space with a couple of mouse clicks. However, be careful: on a typical system, this program will find hundreds of duplicates, but that does not mean that we should delete all of them: some are useful (such as programs that install files into the Windows directory, but keep a copy in their own directory as well). So, only remove the duplicates we are sure that we do not need.

DoubleKiller is a free version and the key benefits and features of it include: DoubleKiller is a fast and easy to use application for finding and removing duplicate files. With this program we can free up hard disk space by removing unnecessary duplicate files; Reduce the time needed for backups or file searches; Tidy up our picture or music collection; Scans directories, complete drives or computers in our Network Neighborhood for duplicate files; Freely combinable comparison criteria (file name, size, date and content); Exclude files based on their name, file type, attributes or size; Presents a list of all identical files so we can decide which ones to remove; Delete the files we chose or moves them to another directory; Allow to export the result list to a text file.

There has also a Pro version which does more sophisticated searching, scans faster, but costs $20. DoubleKiller Pro is faster, offers greater flexibility and a lot of additional features, including: Multilangual interface; Sorting and regrouping results; Check by criteria; Save and reload result lists; Automation via command line.
