I checked your site and the main thing I would suggest is to separate “file access” from the normal content pages. The pages can explain the files, but the actual downloads should be handled with proper rules.
For a safe setup, use clear file categories, limit access if needed, keep download logs, and avoid letting users upload or download anything without checks. If the files are only for learning, it is also good to add short notes explaining what each file is, who should use it, and what risks or rules apply.
For security, I’d also avoid public folders with direct file browsing enabled. Use protected download links, scan files before uploading, keep backups, and make sure users cannot access private folders by guessing URLs.
A simple structure works best: guide page, file description, download button, access rules, and basic safety notes. That keeps the site useful without making file access messy or risky.
