KaleidaGraph is graphing and data analysis software developed by Synergy Software for Microsoft Windows and Apple macOS. Its .qst files belong to the application's graph styling features.
A .qst file contains saved formatting and appearance settings for KaleidaGraph graphs. It is intended to be used within KaleidaGraph rather than as a general-purpose data or image file.
The format is associated with KaleidaGraph and is not commonly supported by other software.
Open a .qst file in KaleidaGraph on Windows or Apple macOS. Use KaleidaGraph to load or apply the style; the file may not open as a standalone document when double-clicked.
There is no known standalone converter for KaleidaGraph .qst files. The style should be loaded and reused in KaleidaGraph rather than converted to another format.
If the goal is to preserve the appearance of a graph, apply the style in KaleidaGraph and export the resulting graph using one of the application's supported output formats.

Record marked as obsolete and not updated for a long time.
Ami Pro was a word processor for Microsoft Windows and OS/2. It was later continued under the name Lotus Word Pro, including a Microsoft Windows version.
An .qst file stores an image used by the Ami Pro quickstart tutorial. It is a program-specific tutorial resource rather than a general-purpose document or image format.
The format is obsolete and is no longer in common use. Its files are most relevant when preserving or running an old Ami Pro or Lotus Word Pro installation.
Open the file with the original Ami Pro software or with Lotus Word Pro for Microsoft Windows, where it may be used as part of the quickstart tutorial.
Because the file is a tutorial resource, it is not normally converted independently.
If the file can be opened by Ami Pro or Lotus Word Pro, the displayed image may be copied or exported from that software when its available functions permit it. Since it is a picture, it may also be a common graphics format with the .qst suffix renamed.

Zelda Classic uses .qst files for quests created for its Zelda-style game engine. In this old game, the .qst file is one of the default file types and represents quest data. A quest can contain maps, game screens, graphics, enemies, items and other game data.
The format belongs to the Zelda Classic software and its accompanying ZQuest editor. Zelda Classic and ZQuest are available for multiple desktop operating systems, including Windows, Linux and macOS.
Quest files remain part of the Zelda Classic ecosystem, although compatibility can depend on the software version used to create the quest.
Open the file with Zelda Classic to play the quest. The file may need to be placed in the location where the program stores or looks for quest files, or selected from the program's quest-opening screen.
To inspect or edit the quest, open it with ZQuest, the editor provided with Zelda Classic. Use a build of the software appropriate for the operating system on which the file is being opened.
There is no general-purpose conversion format for a .qst file. It is intended to be used as a Zelda Classic quest rather than converted to a common game or media format.
ZQuest may be able to open and save the quest for another compatible Zelda Classic version, but compatibility is version-dependent. Keep a backup before saving or modifying the original file.
