Specify the kind of searched file(s) (music, movie, picture) or some of the file attributes (size, date). For documents or data files - a content can be specified. When searching with size range, Scherlokk calculates and displays all folders which fit in the range. Which files can Scherlokk find? Because Scherlokk is not based upon the Spotlight's index, and has its own, powerful search engine, it will find every single file on any accessible volume in your computer. Scherlokk can compare any files (text or binary) and displays their differences, taking into account insertions or deletions. It uses a sophisticated algorithm for finding similar blocks in both files and shows them as a list of differences.
