The hst file extension was used by Yahoo! Messenger, Yahoo's instant-messaging software for Microsoft Windows, for saved conversation history.
These hst files contain details of saved chats and may also include messages that were received while the user was offline. They are local history files used by the Messenger application rather than general-purpose document files.
Yahoo! Messenger has been discontinued, so the hst format is a legacy format and is no longer in active use.
Open an hst file with the compatible legacy version of Yahoo! Messenger for Microsoft Windows, if that software and the relevant user profile are still available.
There is no standard converter for the Yahoo! Messenger hst format. If a compatible version of Yahoo! Messenger can read the file, its history can be copied or transcribed into a common text format.
Renaming the file does not convert it, and conversion may not be possible without the original Messenger software.

Procomm Plus was communications software from Symantec for Microsoft Windows. It provided terminal-emulation and other functions for connecting to remote computer systems.
The HST file contains history data maintained by Procomm Plus. It is an internal support file that belongs to the application's working files and is not a general-purpose text or database format.
This is a legacy format associated with the Windows version of Procomm Plus.
Open the file with the Windows version of Symantec Procomm Plus that created it. HST files are application-specific and may not open meaningfully as standalone files.
Keep a copy of the original file before attempting to open or modify it.
There is no standard conversion utility for Procomm Plus HST files. The file is an internal history file rather than a format designed for interchange.
If the history is needed in another form, use any viewing or export function provided by the original Procomm Plus installation. Otherwise, retain the file with the associated Procomm Plus data.

The HST file contains the current state of a VGA Planets game, including the game universe and the positions and status of its players, planets, ships, and other game objects.
VGA Planets uses the file as part of its turn-processing system. The host software reads the HST file when processing submitted player turns and uses the resulting game state to produce the files distributed to players.
The format is specific to VGA Planets and may depend on the particular host or game version. It is a game data format rather than a general-purpose document format.
Open an HST file with the VGA Planets host software that created or maintains the game. The file is normally placed in the appropriate game directory and loaded as part of the host's turn-processing workflow.
An HST file is not intended to be opened directly in a text editor or media application. If it came from an active game, ask the game's host which VGA Planets software and version should be used.
There is no general-purpose conversion for an HST file. It contains the internal state of a VGA Planets game, so it should be kept with the other files for that game and processed by compatible VGA Planets host software.
Different host or game versions may use different data formats. To move a game to another compatible setup, use that software's own import, backup, or migration procedure if available.
