Why Use Free Duplicate Finder?

Reclaim wasted disk space on your HDD, SSD and speed up your computer by removing duplicate files today. Free Duplicate Finder is a powerful app that uses smart technology to identify all kinds of duplicate files. It’s super simple drag-and-drop interface and intuitive scan modes make removing identical files a breeze!

What’s new in version 5.8.0.1?

The change-log may not seem long,  but this version has lots of improvements. There are some fixes and new features, but performance optimizations are what we value the most. Fast Duplicate File Finder is already the fastest tool on the market, but we continue to improve it with every new release.

Auto-check Longest/Shortest Paths

In previous versions, we provided an option to auto-select duplicates based on file name length. Now we added two more options to extend this functionality –  auto-check by path length. Auto-checking files by path length may be convenient if you compare several folders and you want to keep the files in the one with the shortest or the longest path. There are many ways that you can utilize this new feature. FDFF provides plenty of options that can be used in combination in order to achieve even the hardest goal of automation.

Improved Duplicate Finding Performance

We are always proud to announce performance optimizations. FDFF is already the fastest duplicate remover and improving performance further is really hard. The most important thing for a fast scan is your storage device. Even though FDFF compares data in miliseconds it has to read that data from the storage which is the slowest part of the scan process. Unfortunately, we do not have control over that part as it is a limitation of your hardware.

The optimizations may not be that much, but every millisecond counts when the word comes to comparing millions of files. The average user has more than 300 000 files on the main drive alone. If you add also several external or backup drives that count easily reaches half-million files. So our optimizations include both pre-processing stage and file comparison stage. The first one finds all the files and weeds out the ones that do not need further analysis while the second one performs a deep scan for files that are possibly duplicates.

Improved RAW Image Preview

Though FDFF is not a duplicate photo finder, for which task we have a dedicated tool, it is able to preview many multimedia files. We have added some extra RAW formats that are now supported for new camera models.

Bugfixes

Well, nothing too important here. You know that we test thoroughly all duplicate removal algorithms so no bug can sneak in there. There were some very minor discrepancies in the exported file structures. For example, the file name and file size attributes were swapped and the file name field contained the full path instead of only the file name.

Download the latest version and give it a try. Let us know if you feel the performance improvements.

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.

Fast Duplicate File Finder 5.4.0.1 – Autocheck Shorter/Longer file names

Fast Duplicate File Finder 64 Bit Version

MindGems Duplicate File Finder New Auto-Check Features

Fast Duplicate File Finder is recognized as the the fastest and the most reliable duplicate finder on the market. Any tool that claims faster performance compares MD5, CRC, size, dates, names or other unreliable properties which may lead to incorrect results and loss of valuable data.

Fast Duplicate File Finder (FDFF) performs real byte-to-byte comparison and guarantees that the identified files are 100% duplicates. If a tool finds more duplicates than FDFF that is not a sign of better performance – it is a sign of poor detection algorithm and one should really check the results provided by such tools deeper with a proper DIFF tool or a HEX editor.

Download: Duplicate File Finder

New Auto-Check Features

The auto-check feature in the duplicate file finder is redesigned and includes options to auto-check files with shorter or longer file names. This is really handy in cases of files with prefixes or sufixes like Copy (X) of or Filename Copy (x).ext. The tool can now mark automatically the files based on the file name length. It is possible to keep the file with the shortest name or the one with the longest.

As the list of auto-check options grows larger and larger we have now grouped them in a drop-down list. It includes:

  • Smaller File Sizes
  • Bigger File Sizes
  • Older File Dates
  • Newer File Dates
  • Shorter File Names
  • Longer File Names

More auto-check options will be added as needed.

This version also includes a fix for a crash that was caused if a damaged DNG file was previewed. A fix for “Protect system files and folders” option is applied. In some cases if the option was enabled certain sub-folders in the “USERS” folder were not included in the scan.

High Performance 64 Bit Version

FDFF is already the fastest duplicate file finder on the market, that performs a proper duplicate scan that does not report false positive or miss duplicate files. The latest version provides support for 64 Bit operating systems making the tool even faster and capable of handling larger file lists. The installer will automatically install the proper Duplicate Finder version depending on the user’s operating system. This version also lifts the memory limit that is present in the Windows operating systems for 32 Bit applications running on a 64 Bit operating system.

Preserve group integrity on sort

While this feature was already available in the tool it was always enabled by default. What actually means “Preserve group integrity is that regardless of the column that is sorted the items from the same group would always stick together. This of course is well necessary in order not to accidentally delete all items from the same group, but in certain cases it is more convenient to sort by certain file property like path, mark all items and “check” them for move delete. After that the option can be restored back and sort the items over by preserving the group integrity.

Extremely Faster Save/Load/Export to XML on large projects

The save, load and export functionality was redesigned in order to better cope with huge file collections. The claim “extremely faster” is not over-exaggerated as the tool may perform the mentioned actions hundreds of times faster depending on the size of the corresponding list. A million files for example are loaded, exported or saved in seconds.

New Duplicate Finder Features

Exclude Folders or Subfolders From Auto-Check

A new feature in the “Advanced auto-check” options – “Match full path” makes it possible to exclude multiple folder names from the auto-check feature by specifying patterns with wildcards or folder names. While there is an option to exclude a folder from auto-check in the folders list, the new feature provides a more flexible way of doing that. Also the new option makes it possible to specify subfolder names that are not listed in the folders list. Multiple patterns or folder names can be specified by separating them with a vertical line ( Symbol: | ).

Backup Duplicate Files

While the main goal of a duplicate finder is to remove duplicates there are certain cases where duplicates should be intentionally copied/duplicated. These usually are required for backup/sync purposes. The new option “Copy checked files” helps exactly in such cases.

Additional improvements in the Copy/Move/Delete panel make it easier to read and configure.

  • Extended date options in Auto Check, Filter, Quick Check and Exclude from Auto Check, so that created, modified or last accessed file date can now be used.
  • Added separate columns Created, Modified and Accessed to show each individual file date.
  • Created, Modified and Accessed file dates are saved to the exported projects.
  • Fixed – similarity slider can be now increased to 100% using the mouse.
  • Fixed order of duplicate groups – preserved on load/save
  • Fixed loading projects where decimal separator is different from the current locale decimal separator.
  • Fixed moving files from UNC paths like \\Server\Path\

The Key New Features Of The Duplicate File Finder Tool

Filtering Duplicate Files by Accessed, Created And Modified Dates

The Created, Accessed and Modified dates are a property of every file and folder. The tool utilized only the Modified date in the past, but sometimes using the Created and Accessed dates may be necessary. Fulfilling the wish of our users we have added all the three dates in the application. The Modified, Accessed and Created dates are now listed in the results table. Of course if one does not need all those dates, they can be easily hidden in the application settings in order not to clutter the display.

The corresponding changes are applied everywhere in the application and those include the Filter Dialog, Auto Check, Quick Check and Advanced Auto Check options.

The newly added date fields are also included in the export features.

This release fixes also some bugs and provides improvements. An issue that prevented the move operation on network shares in certain cases is now fixed. An improvement in the project save/load functionality preserves the groups order. A fix for the similarity slider makes it possible to set 100% using the mouse buttons or wheel – this was possible only by typing the number manually in the past releases.

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.

Version 4.0.0.1 of The Popular Fast Duplicate File Finder Is Released

This new release provides some fixes and two new features. There are two new context menu items in the results list.

The first one “Remove from List…” will remove the selected items from the list. After the remove operation if the group contains only one item it will be automatically removed if the option “Remove from list groups containing single file after move/delete”. This handy new feature can be used to remove items that should be kept from the list. Please note that this feature removes just the item from the list – not the actual file.

The other option is  “Remove Group from List…”. Using the feature will remove the entire group to which the selected item(s) belongs. Multiple items can be selected and removed at once.

The fixes include a modification that enabled the tool to load projects with older file formats. Deleting large amounts of files is optimized in this release and handled better and faster. An issue that prevented the program form showing results when using vertically rotated desktops is now removed. Associated file icons are now retrieved in faster and safer.

Find Duplicate Files That Have Names in Multiple Languages Simultaneously – Full Unicode Support

While Fast Duplicate File Finder could scan files named in any character set (Language) it could scan only two languages simultaneously. The default one in your system and the one set for non-unicode applications. While this is not an issue for most of the users now this limitation no longer exists. The application is capable of listing results in any alphabet simultaneously. For example you can have files in Chinese, Greek or Arabic language listed in the results at the same time.

Preview Duplicate Microsoft Word (doc) and Excel (xls) Files

There is a support for XLS and DOC files right inside the Duplicate File Finder’s preview window. This feature requires the corresponding Microsoft Word and Excel applications to be installed on the computer. As loading large doc and xls files can take several seconds ( this is something that depends on the installed Word and Excel applications ) there is an option to disable the preview for them in settings.

Improved Folder Comparison Features

The “Exclude From Self Scan” and “Disable auto-check for this folder” items are now listed as check-boxes inside the folders list. That helps to easier visualize the configuration of the current project. The two features are handy when one needs to merge two or more folders and set one or more of them as “Source”. The “Exclude From Self Scan” option denotes that the files inside that folder will not be compared with each other. They will be compared only with the file in the rest of the folders that are added in the project. The “Disable auto-check for this folder” is pretty self-explanatory – if the auto-check feature is used the items in the folder will not be marked.

Improved Duplicate Files Sort

Sorting duplicate files in past versions was performed inside the groups in order not to break the group integrity. It would not make any sense to have the files sorted by size and have files from different groups listed together. The new improved sort will sort the items inside the groups as in past versions and also sort all groups keeping the items inside together. Now if you sort the items by size in descending order the groups that contain the largest items will be listed firs.

Find Duplicate Files With Same Name or Similar Name and Different Extension

The “Similar File Names” search mode now includes an option “Do not compare file extensions”. This tells the application to compare only the file names without their extension. This is handy in order to find duplicate files like  “Beat It.mp3”, “Beat It.wav”, “Beat It.ogg” or “Wedding.avi”, “Wedding.mp4”, “Wedding.mkv” and so on. An extremely handy feature that can find multiple versions of the same file that are converted to different file formats.

Additional Duplicate File Finder Improvements

These include faster delete/move operations on large amount of files. Improved scan speed for folders that contain large number of files. The information panel above the results grid is now updated after every delete or move operation. There are a lot of other small GUI fixes and enhancements that are not worth mentioning.
