If it is a folder that you need to copy, make sure SRC_PATH ends with / (considering DEST_PATH on the container does exist already)

sudo docker cp /home/desarrollo3/proyectos/web2015/ 4aefd670e41f:/var/www/html/web2015

docker cp mentions:

SRC_PATH does end with /.

the content of the source directory is copied into this directory.

As shown in issue 13171, the error message "Error: Path not specified" was fixed in docker 1.8.0 (commit 5e86b81).
Docker 1.6.2 is way too old.
