コモンズ素材名直送ツール is a Chrome extension that allows users to download materials from NicoNico Commons with the material title and creator name added to the filename. Additionally, it offers the convenience of automatically copying the material name.

By default, when downloading materials from NicoNico Commons, the filenames are usually just IDs starting with "nc," making it difficult to identify the content of the material. This tool solves that problem by modifying the response header when downloading materials, resulting in filenames with the material name included.

The extension also provides a feature to automatically copy the material name and ID when the download button is pressed, which can be useful when adding BGM names to videos, for example. Please note that this feature is disabled by default.

Furthermore, the extension allows for automatic redirection to the material page when searching for a material's Commons ID using keywords.

The extension provides options to enable or disable the material name copying feature, as well as customize the format of the default filename and copied text. It even supports Japanese characters, allowing for formats like "コモンズ素材_${id}_${title}."

Please be aware that the functionality of this tool is based on the specifications of NicoNico Commons at the time of its release and update. If NicoNico changes its specifications, the tool may cease to function properly. Additionally, if the download button is clicked before the material page finishes loading, the filename modification may not take effect.
