# import_file_to_cache

astropy.utils.data.import_file_to_cache(url_key, filename, remove_original=False, pkgname='astropy', *, replace=True)

  Import the on-disk file specified by filename to the cache.

  The provided `url_key` will be the name used in the cache. The file should contain the contents of this URL, at least notionally (the URL may be temporarily or permanently unavailable). It is using `url_key` that users will request these contents from the cache. See `download_file()` for details.

  If `url_key` already exists in the cache, it will be updated to point to these imported contents, and its old contents will be deleted from the cache.

  Parameters:
    url_key `python:str`

      The key to index the file under. This should probably be the URL where the file was located, though if you obtained it from a mirror you should use the URL of the primary location.

    filename `python:str`

      The file whose contents you want to import.

    remove_original bool

      Whether to remove the original file (`filename`) once import is complete.

    pkgname `str`, optional

      The package name to use to locate the download cache. i.e. for `pkgname='astropy'` the default cache location is `~/.astropy/cache`.

    replace bool, optional

      Whether or not to replace an existing object in the cache, if one exists. If replacement is not requested but the object exists, silently pass.
