Arrow Some antivirus software might falsely report that downloaded files are infected with a virus. If this happens please send me an e-mail containing the name and version of your antivirus and the name of the detected threat so I can report the error. As a side note, the files are always scanned before being uploaded to Bytessence.com.

Bytessence DuplicateFinder

Bytessence DuplicateFinder is a freeware program designed to detect clones of the files stored on your computer. Duplicate files have a negative impact over your system's performance because they waste valuable space, they increase the antivirus scan time, they make defragmenting take ages and they make it harder for you to organize your files.

BDF employs optimized detection algorithms and file filters so the scanning time is greatly minimized. The detected files can be removed in no time with the help of the automatic file selector and the predefined set of actions (copying, moving or recycling).

Frequently asked questions

Q: How to translate BDF?
A: To localize BDF you can open the file called 'English.ini' from the 'Localization\' directory of your BDF installation and translate the lines. The files use the standard INI layout so you can use any raw text editor for translation (like Notepad). To make the job easy you can use IniTranslator, an open-source translation utility. After you finish, save the file with UTF8 encoding. If you want to share it with other users you can send it in an archive at the support e-mail (see the contact page) and it will be published here.
Q: How to install translations?
A: To install translations, unpack the archive to a temporary location (like the Desktop) and copy the extracted .INI file to the 'Localization\' directory of your BDF installation (for example 'C:\Program Files\Bytessence DuplicateFinder\Localization\'). After copying the file, restart the program if it was running then open the Settings dialog. At this time you should be able to see the name of the installed file in the drop-down list. To activate it, select the desired language and press 'Accept' to save the settings and load the new language. The changes will take place instantly.
