Duplicate files often exist when Internet users download files to their computers, especially when they use robot to download all files within the URL. An unofficial survey indicated that about 10-20% of files can be regarded as duplicate in a common file system. For instance, in your 40 GB personal data, around 4-8 GB disk space is wasted in this scenario. In some report from NoClone user, they can find up to 300 GB data in a single search session, which is already the total size of a typical hard disk!
At the same time, duplicate files can also mess up your file system and make it difficult for you to find what you need quickly among the thousands of files, among which there are duplicate files as well as modified files with the same name.
Buying a new hard drive or writing the duplicate files to CDR may solve the problem, but more and more space is required as a result. File collection without management will grow endlessly. Therefore, files should be managed by uncovering duplicate files and then deleting/archiving them.
In corporate computer, documents of different versions are kept for various purposes, e.g. minutes, accounting documents. These files are not exact duplicates, yet it is unnecessary to keep them all. By uncovering these similar files, you may sort out the unique files and keep them for backup.
All too often, we use USB thumb drive or other mobile hard drive to edit documents on different computers and would easily forget which documents are changed. In this case, you need to uncover these similar files and save the version you want.
NoClone 2010 Duplicate File Finder is a power tool that will help you manage the duplicate files in an effective and efficient way.
Using True Byte-By-Byte Comparison, NoClone scans duplicate files regardless of folder structure and ensures that the duplicate files uncovered are exactly the same in content. Some may argue that Byte-by-Byte comparison is slow and not efficient. However NoClone optimized it to an efficient algorithm as good as MD5 hashing comparison. Instead of comparing files one by one, NoClone filters a list of suspected duplicate files with same file size and type. Then those files will be opened and NoClone reads blocks of data and compares. Files with all blocks matching indicate that they are duplicate files. With above algorithm, each file is opened once for comparison, which is the same as MD5 hash comparing methods.
In addition, NoClone provides up to 11 search options for your selection. For instance, NoClone can uncover exact-content duplicate files, duplicate MP3 with different sampling rate or tag data, duplicate images, zero-size files, duplicate Outlook emails, etc. NoClone can also uncover similar files with its Powerful Fuzzy Match function.
As a new feature of NoClone 2010, the search option Compare Folders is now available for the purpose of file synchronization, hence you can compare folders in USB thumb drive/other mobile hard drives with those in your computer.
In NoClone 2010 Free Edition, you can enjoy all the above features except Smart Marker – a tool that helps user mark duplicate files by date, version, size, folder and file name pattern, and Mark All Except One – an option provided for safety issue.
