# Check that the user space is clean after checks

Have you faced a note on CRAN about non-standard things in the check directory ?

    Check: for non-standard things in the check directory
    Result: NOTE
        Found the following files/directories:
         ‘extrapackage’

Maybe you do not understand where these files came from.
Then, you can run `check_clean_userspace()` in your package directory to detect every files that you created during the check.
They could be issued from examples, tests or vignettes: `check_clean_userspace()` will tell you.

    #' \dontrun{
    # This runs a check of the current package
    all_files <- check_clean_userspace()
    all_files
    #' }
