In the early 2000s and 2010s, numeric filenames were the standard for file-sharing forums and bulletin boards (BBS). These sites used automated scripts to rename uploads to prevent duplicate entries and to obscure the contents from early search engine crawlers.

If you'd like to dive deeper, let me know: Is this a specific file you found on your computer? 23708.rar
