Importing Animation and Blueprints from another project

i tried to export my animation and blueprint from other project but there was only two options either T3D or COPy but when i tried to import to my other project there was no option to imort T3D or COPY is there something wrong?

Open your first project, right click on your assets (blueprints, animations) and choose migrate. Finally specify directory to your second project. Done!

when i choose migrate it only shows folders that contained in my firs project

nope solved it XD
