Fastest Duplicate Finder – FDFF 5.5.0.2

Fast Duplicate File Finder has proven to be the fastest duplicate finder on the market. As we provide a free version, it is used by millions of users. They have used and tested it for more than a decade. Therefore it is a reliable bug-free tool that has proven itself over the years and is the number one choice of many professionals.

Although there is not much to improve we are always trying to squeeze up as much as possible and improve the performance further. This release improves performance and fixes a minor annoyance. There was an issue where the progress-bar was displaying “100%” for a very long time. This is not something that had to do with the quality of the scan or results. It was only a display problem, but some users thought that the application was stuck especially when scanning large drives.

Fastest Duplicate File Finder – Scan Methods

  1. 100% Equal Files – This is the best mode for a proper duplicate scan. While it is not the fastest of all the supported modes, it is the one that guarantees to list true duplicates. Many tools on the market may perform faster as they use CRC checksums. Such tools produce incorrect results and may lead to permanent loss of data. For example, the CRC or checksum of the file that many such tools are using may identify completely different files as duplicates.
  2. Similar Files – This mode can find similar documents. It is very precise, as a result, it is the slowest of all. In short, you should use it on a smaller subset of files. This is mode can find similar excel, word, txt, pdf, archive and other documents. It can not find similar photos or similar audio files. This article: Which Duplicate File Finder To Choose? explains why we have developed dedicated tools for those tasks.
  3. Similar File Names – this is a fast scan mode that can find similar or duplicate file names. For example, it is useful if you want to find files that are named like: “My Essay (1).doc”, “My Essay March.doc”, “My Essay 2019.txt” and so on. A tutorial for the above two modes is available here: Find Similar Files and Similar File Names
  4. File Size – searching for duplicates by file size is not a reliable method. However, in many cases, it can be helpful. It is extremely fast and you can use it for very large drives. If the files are large the chance for two files to be different and to have exactly the same size gets very low. In conclusion, for large files it is acceptable to use it. As always we do recommend that you review the results prior to removing any files.

The Key New Features Of The Duplicate File Finder Tool

Filtering Duplicate Files

A handy new option is added in the filtering dialog that makes it possible to filter folders by a phrase including wildcards. For example if the text “copy” is added – all the folders that contain “copy” in the name will be matched. Combinations of phrases can be used by separating them with a vertical line e.g.: “copy|backup|bckp”. In this example along with the folders that contain the phrase “copy” in their name will be listed also the ones that contain “backup” and those that contain “bckp”. A more sophisticated example is “b??(*)*” – it will match all folders starting with “b” followed by two characters then an opening bracket followed by one character and then a closing bracket followed by any number of characters. If the example is not clear enough the asterisk denotes that zero or more characters should be present and the question mark denotes that exactly one character should be present at that position. The combinations are endless and it is easy to match any folder’s name with high precision. Here is a screenshot of the new filtering window:

Duplicate File Finder User Interface And Features Improvements

Clicking on the folders grid header icons now checks/unchecks all folders for either exclusion from “Auto-check” or from “Self-scan”. The browse for folder dialog is updated so if no folders are marked, the currently selected folder is added. This makes it easier when adding a single folder to the list.

There is a hex error code for every delete/move file operation that fails. This makes it easier to identify the problem e.g. if the files is in use, if the user account used to start the application does not have sufficient permissions to manipulate the file, it he file is stored on a read only media and so on. All the error codes can be found at the Duplicate File Finder FAQ page

A new option to Keep Folder Structure while moving files is now added to the application. In the previous versions it was always ON by default. This new feature also takes care of file name conflicts in cases where two or more files with the same name from different locations are moved to the same folder. If the file “report.doc” for example is moved to the same folder from multiple locations the extra copies will be moved with the name “report (1).doc”, “report (2).doc” and so on.

Earlier versions of Fast Duplicate File Finder ignored the desktop folders if the “Protection for system files and folders” was enabled in settings. (This option is enabled by default in order to prevent damages to the operating system by novice users). Current version will scan the desktop folders even if that option is enabled as many users store their files on the desktop. In order to prevent damages to the desktops of other user the application will ignore shortcut files which are intentionally duplicated over the desktops of every user. E.g. two different users can have shortcuts to the same applications.
