FileMatrix is a multi-dimensional file manager which gives you the ability to navigate, organize and manage files effectively. The FileMatrix name comes from the fact that files are organized like a 3 dimensional matrix of files (files in a column, columns in a board, boards in the program).
This matrix gives you the power to quickly organize in groups the directories in which you navigate often, particularly by putting several directories side by side, and let's you access later each group with just a click of a button.The designed usage for FileMatrix is for the cases when you want to have several directories displayed side by side, either to see their contents simultaneously or to speed up copy / move operations among them.
To be more specific, if you want to manage and navigate through your pictures, FileMatrix's multi-column view and navigation style is the best system you can possibly use. This has nothing to do with a program being better than another, but with a system being better for this specific task.
