The Itch.io app is consuming all my storage space.  On sifting through the download-location, I find old versions of games still in place and uselessly consuming space.

1. I assume I can safely delete these files using the usual filesystem tools (`rm -rf [dirnamea]`) without interfering with application function?

2. Please fix this, or include the option to delete-old in the per-game manager interface.

Thanks a bunch!
