The size of movie is 192MB & 42 minutes long; how do I break it down into segments so I can attach to email or share on facebook?

There are many of my friends all across the U.S. who have shown a desire to comb through my personal music memorabilia. As a rookie with no formal education in the area of computers, nor have I been able to find out how to create a useful method of compression that would allow the person tools to open and view the compressed files without some hassle. I do not have a clue about decreasing the size of my movie so I can share in email or facebook! While I'm asking, does anyone know how to create a link that one could simply click on and be carried to the file for viewing? That form of granting access to my creations automatically would be ideal?

Thank you to anyone who may be able to share a solution to this problem! McDsPlace
