How can I merge two compositions from different projects? [Locked - duplicate thread]

[Guest]

I worked on two compositions in separate After Effects files (a 6 second and a minute composition). How can I merge the compositions in a new composition so that the minute long composition will follow immediately after the 6 second composition?

Projects can be imported into other projects like any other file type. that's all you need to know.
