Most files of the following command output will be lock-files and place holders created by other applications.
# find ~ -empty
List all the empty files only in your home directory.
# find . -maxdepth 1 -empty
List only the non-hidden empty files only in the current directory.
# find . -maxdepth 1 -empty -not -name ".*"
