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.

The Fastest and The Most Precise Free Duplicate File Finder Just Got Even Better and Faster

MindGems Inc. tools are recognized for their quality and performance and the FREE Fast Duplicate File Finder makes no exception. Version 3.7.0.1 of this popular freeware duplicate remover tool adds even more features and performance improvements.

Two search modes in this release are optimized. The improvements in the “100% Equal Files” mode are tremendous when scanning large file volumes. The improved algorithm can be thousands of times faster depending on the quantity and size of the scanned files. There are huge performance optimizations also for the auto-check and the final stage of the scan where the application required longer time to finalize for large quantities of files.

The “Similar Files” mode which is available in the PRO version of the product is now also optimized and more stable. Nevertheless let me remind here that this is not the commonly advertised FUZZY search method that provides low quality results. The search for similar files inside Fast Duplicate File Finder PRO performs advanced algorithms in order to find truly similar files and can recognize two similar documents even if entire paragraphs are rearranged.

Some additional command line options are added to the PRO version of the tool in order to help with the automation of duplicate finding tasks. To the already present -run option our developers have added the options -s and -exp.

-exp <semicolon delimited list of export formats> – Export command line parameter. Depending on the file extension will export the corresponding file type. Multiple formats can be exported at once by separating the paths with semicolons. The variables {DATE} and {TIME} will be replaced with the current date and time.

-s – stands for SILENT. Using the option the GUI will not be displayed during the scan and the application will exit after the command line actions are processed.

Example: DupFileFinder.exe -run -s -exp “c:\result_{DATE} {TIME}.xml;c:\result_{DATE} {TIME}.fdff;c:\result_{DATE} {TIME}.csv”

The {DATE} and {TIME} variables are useful to keep track of the scan data and tag it with the corresponding date and time.

While Fast Duplicate File Finder is a great free tool, I would recommend you to check also the dedicated duplicate photo finder and duplicate music finder tools that are designed to organize photo and music collections. While Fast Duplicate File Finder can find duplicate files of any type you can read here why we provide dedicated duplicate finder tools.

Version 3.5.0.1 of Fast Duplicate File Finder is released and available for download. Along with all the new features the new version provides improved support for the Windows 8 operating system.
A major new feature in this release is the option to find duplicate or similar file names. Such feature is handy for identifying copies of the files with appended numbers or letters in order to denote versions. The “Similar File Names” mode will list for example all files named “My CV.doc”, “My CV 2.doc”, “My CV 2012.doc” and so on. You can control how close the matched names should be by specifying the similarity percent. Usually a setting of 95% works quite well.

Another important option is added to the filter where now you can not only exclude certain types of files, but also include them . The new version will let you scan for example only for certain types of files like “*.jpg”, “*.exe” or a combination of them. There are also plenty of other filtering options that you can choose from.
