Problem: A client needed a repeatable desktop tool to collect attachment files from large forum sections where many download links were hidden, visually obscured, or not directly exposed as standard file URLs.
Challenges: The target pages required browser-level discovery, while downloading everything through a browser would be slow. Attachment links were partially hidden behind page structure, relative URLs, Discuz attachment parameters, duplicate threads, invalid HTML error pages, and large-volume file organization requirements.
Solution: Built a two-stage automation system: Selenium with headless Chrome discovers forum thread URLs from listing pages, then a multi-threaded Requests and BeautifulSoup pipeline parses each thread, removes reliance on visible click areas, detects hidden Discuz attachment endpoints such as forum.php?mod=attachment, converts relative paths into full download URLs, downloads files concurrently, validates file structure, and archives results into batch directories.
Result: Automated a repetitive manual collection workflow, enabled hidden attachment link discovery and download, reduced duplicate processing with persistent history tracking, improved throughput by separating browser discovery from HTTP downloading, and made the process usable by non-technical operators through a Tkinter GUI.
