In order to run the tool one should define a range of integers [0, maxSize] by specifying maxSize and a step.
The range of integers is divided into segments of size step: [0, s_1, ..., s_n-1, maxSize].
The tool calculates how many files in the system fall into each segment [s_i-1, s_i).
Note that files larger than maxSize always fall into the very last segment.
The result is a two column table. The first column represents segments and the second contains the number of files in it.
The results can be easily visualized using Excel, R system or other graphing software.
