Automatically clean up cached downloads

Background

According to the documentation, the download_dir directory "is a temporary cache, and can be cleaned up from time to time."

Details

If the download_dir directory is a temporary cache, wouldn't it make sense for the default to be %TEMP%\Python (or something similar), rather than a subdirectory of the global_dir directory?

Why?

1. Files in %TEMP% should be assumed to be temporary (hence the name), so wouldn't it make sense to put temporary downloads there?

2. Files in %TEMP% are, I believe, subject to the Windows automatic "clean up temporary files" feature, aren't they? In this way, old downloads would get cleaned up automatically, wouldn't they? (I'm not an expert on this feature, so I may be all wet here.)

I'm new to this project, so I'm sure others will set me straight if I'm way off here...

Commencez par retracer où les valeurs par défaut de download_dir et global_dir sont définies et lues, et consultez la documentation liée sur la configuration administrative de Windows. Vérifiez comment le nettoyage des fichiers temporaires de Windows s’applique à l’emplacement proposé ; le travail sera considéré comme terminé lorsqu’un emplacement par défaut convenu, un comportement documenté et des tests ou une vérification de la configuration résultante seront disponibles.
