JDownloader directory files folders and cleanup
This article describes which files/folders can be found in your JDownloader installation directory, the purpose of those and whether or not you can delete them.
While JD should keep its installation directory clean, it is not perfect in doing so and the older your installation is the higher the chances are of it containing obsolete files.
If you feel the need to clean that directory or if you're just curious what's the purpose of those files/folders, this article is for you.
Some warnings:
Close JDownloader before you attempt to delete any files!
