What is an HST file?
Contains a history of events related to a specific program; similar to a .LOG file, but may be used for a broader range of purposes.
HST files are created by various programs including Corel WordPerfect (for spellcheck updates), Symantec Anti-Virus (for virus definition updates), Garmin MotionBased (for tracked GPS data), Netscape (for Web browsing history), and Yahoo! Messenger (for chat history).
