Upload Detailed resume?

I have two version of my resume. One is single page resume. Another one is a two page detailed resume that goes in depth of my recent roles. When I am applying job, the application has option to upload resumes/CV files. Should I upload both resume? First file title is "Joe Smith Resume" second file title is "Joe Smith Resume Detailed"? I am a Mechanical engineer with 8 years experience. Thank you!
