yes, it is possible although it seems like a bit of a stupid question to ask really as that is what a rectangular does, note the file is not for steel it can only be used on soft aluminum and soft metals such as copper. steel and iron would simply wear out the file and probably make sparks too.
A rectangular file is commonly referred to as a "flat file" or "rectangular file." It is a type of hand file characterized by its flat and rectangular shape, used for smoothing or shaping materials, particularly metal and wood. The flat surface allows for effective filing on flat surfaces and edges.
You could use strong, sharp plastic tools on wood, but not on metal.

A fine cut file is used for filing down wood and other materials. It is also used to smooth the edges of materials such as wood, metal or plastic.
