Definition - What does Hotfile mean?
Techopedia explains Hotfile
In terms of security features, Hotfile users may be required to use a CAPTCHA feature in order to prove that a human is seeking access to the service, rather than an automated system. CAPTCHA generally requires inputting several letters that are shown in a sequence on the user’s screen. Problems with excessively complicated CAPTCHA requests have been frustrating for some users of technologies that verify the feature.
