With today's huge hard drives it becomes easy to accumulate large collections of files. This becomes a problem when you realize that your collection of 50,000 files is full of duplicates... Sorting this manually would take weeks. TwinSeek however will speed this up significantly by comparing all the files in a directory and its subdirectories and will then show what ones are 95% similar. It can then show some details on the files to help you decide which ones to keep, or TwinSeek can even delete all doubles with one button. TwinSeek can also used to provide a detailed comparison of the differences between two files.
