Open Directory Downloader
Indexes open directories listings in 100+ supported formats, including FTP, Google Drive, GoIndex (alternatives).
Written in C# with .NET (Core), which means it is cross platform!
Downloading is not (yet) implemented, but is already possible when you use the resulting file into another tool (for most of the formats).
Downloading with wget:
wget -x -i theurlsfile.txt
Downloading with aria2c (Does not support directory structure..):
aria2c -i theurlsfile.txt
If you have improvements, supply me with a pull request! If you have a format not yet supported, please let me know.
