How To Get Rid Of Duplicate Files In Windows 7

Duplicate Files Finder is a cross-platform application for finding and removing duplicate files by deleting, creating hardlinks or creating symbolic links. A special algorithm minimizes the amount of data read from disk, so the program is very fast.

Features

  •     Byte by byte comparison
  •     Fast search
  •     Support for hardlinks and symbolic links
  •     User interface for deleting files and creating links
  •     Many search options

The algorithm is as follows: First, all files are sorted by their size, because files can be only equal, if they have the same size (logically).

Then the files are compared with each other, and thus the equal files are determined. If two files are not equal from a given point on, reading is interrupted; no more has to be read for determining that these files are not equal.

Because of this the results are determined much faster than in programs which use hashing algorithms, for which all files have to be read completely.
Additional caching of the contents of the files additionally improves performance.

Using Duplicate File Finder gives you an easy way to organize your digital media collections.
