Unable to install pytorch with a downlodad file

How do I install with Conda a downloaded file from:
https://anaconda.org/pytorch-nightly/pytorch/files

File is:
pytorch-2.5.0.dev20240813-py3.12_0.tar.bz2

File is downloaded, but how do I get conda install to use this file?
When I double click the file it extracts to a directory.
