astropy.utils.data.export_download_cache(filename_or_obj, urls=None, overwrite=False, pkgname='astropy')[source]

Exports the cache contents as a ZIP file.

filename_or_obj : str or file-like

overwrite : bool, optional

If filename_or_obj is a filename that exists, it will only be overwritten if this is True.

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.
