ComfyUI Node: Url Download

Url Download:

The TY_UrlDownload node is designed to facilitate the downloading of files from a specified URL directly into your local system. This node is particularly useful for AI artists who need to quickly and efficiently download resources such as images, models, or datasets from the internet without leaving their workflow environment. By automating the download process, it saves time and reduces the risk of errors associated with manual downloads. The node ensures that files are saved with unique names to prevent overwriting and can handle large files by downloading them in chunks, providing a progress bar to monitor the download status.

Url Download Input Parameters:

url

The url parameter is a string that specifies the web address from which the file will be downloaded. This is a required parameter and must be a valid URL. The node will parse this URL to determine the file's name and extension. There is no minimum or maximum length for this parameter, but it must be a properly formatted URL.

filename_prefix

The filename_prefix parameter is a string that allows you to specify a prefix for the downloaded file's name. This helps in organizing and identifying files, especially when downloading multiple files. The default value for this parameter is "TyDev". There is no strict limit on the length of the prefix, but it should be concise and meaningful.

save_file

The save_file parameter is a boolean that determines whether the downloaded file should be saved permanently or temporarily. If set to True, the file will be saved in the output directory; if set to False, it will be saved in a temporary directory. The default value is True. This parameter helps manage storage and file organization based on your needs.

Url Download Output Parameters:

file_path

The file_path output parameter is a string that provides the full path to the downloaded file on your local system. This path includes the directory and the uniquely generated filename. This output is crucial for subsequent nodes or processes that need to access the downloaded file.

Url Download Usage Tips:

• Ensure the url parameter is a valid and accessible web address to avoid download errors.
• Use a meaningful filename_prefix to easily identify and organize your downloaded files.
• Set save_file to False if you only need the file temporarily, which helps in managing disk space efficiently.
• Monitor the progress bar to track the download status, especially for large files, to ensure the process completes successfully.
