Total Commander

The search dialog could be improved with an option to only read a certain amount of kB in each file from the start or end of it. The size could be selectable or preset. This would enable fast, universal, adaptable searching in metadata tags in various formats, without having an program with specific support for that file type, and tag structure, and avoid wasteful reads or false matches.

I apologize if there already is such a feature and I haven't seen it yet. Total Commander is very big and customizable already.
