One of the defining characteristics of bitdownload.ir is its distribution method. Instead of using torrent files, the site primarily provides direct download links hosted on its own servers (e.g., s2.bitdownload.ir ). These links often lead to compressed archives, typically in RAR format, which are protected by a password. The standard password for these files is either bitdownload.ir or www.bitdownload.ir . This practice of password-protecting the archives serves a few purposes: it adds a layer of obfuscation to evade automated takedowns, ensures that the source of the file is known to the downloader, and can be used to drive traffic to the website.
