SoftChronizer is a very easy-to-use duplicate file-search utility for many types of files, that was not exclusively designed to keep your PDF file collection, MP3 file collection, or your collection of pictures in order, but in fact does just that!
SoftChronizer can reliably search for any kind of duplicate file in as many directories as you have stated. The program uses either the highly accurate "Byte-by-Byte" search, or the very fast "Fuzzy-Logic" search option, which uses, among other features, -- for the first time in a duplicate file-search program, -- the sophisticated and configurable "Levenshtein-Distance" Algorithm (Vladimir Iossifowitsch Lewenstein, Russian mathematician, 1965) to Detect duplicate FileNames. - SoftChronizer allows you to search for thousands of file-type combinations that you can compose by yourself as "Quick Start Buttons" and add them to the main window. Pre-defined buttons for PDF files, MP3 files and the most common image-files, and for a complete file-search for all file-types are already available.
SoftChronizer supports the display of MP3 ID3 tags (displays the bit rate, i.e. a statement about the quality of the music, as well as the duration of a track in minutes and track- & album-name of a song), as well as displaying the image-sizes in pixels and the color-depth of all images! - So if you see several duplicates, you quickly can decide what picture, or which MP3 file you want to keep, or not. - The selected files then either can be permanently deleted "in a swing", moved into the Windows* Recycle Bin, or moved to the previously specified directory.
For each button, for each control, SoftChronizer shows you detailed help text in its status bar, at the bottom of each window.
SoftChronizer also works very quickly: it only needs about one minute for 14,000 files (30 GB size, "Byte-by-Byte" scanning) and only some seconds for the same "Fuzzy-Logic" scan (filename string-comparison).
