Is there any file attacher programs?

Question

Ok, is there any file attachers?

example:

there are 2 files with diffrent types and one type is .amt and the other is MG INC.

How would I beable to attach these programs? like make them into 1. And attach the programs together. (btw they will fit if attached, cause its codings comply.)

Is there any program that can do this?

if so, could you plz tell me? I will choose a best answer if it works.

~Thank You

Using the command prompt, you can give the command:
copy file1.ext + file2.ext (newfilename.EXT) and hit enter. Disregard the parenthesis marks, and put in the correct file extensions in place of where I've put .ext in the command.
