Save complete project?

It is possible to save complete project (libraries) to open it in other machine that does not have all the libraries? Thank.

As an incomplete answer: every project stores a “project cache library” (both for schematic and footprints) locally. So it can open that project and display all symbols. That cached symbols (/or footprints) can be reused.

If you need new symbols that are not cached, you have to provide the library.
