# OPTIONS

This document summarizes the current repository's advanced configuration options.
All options are stored in XML config files under QuickLook data location:

- `%APPDATA%\pooi.moe\QuickLook\` for installed mode
- `UserData\` next to the executable for portable mode

Each config file is named after its domain, e.g. `QuickLook.config`, `QuickLook.Plugin.ImageViewer.config`, `QuickLook.Plugin.VideoViewer.config`.

## Config file format

The config file is a simple XML document. If the file does not exist, run QuickLook once and then create it.

Example:

```xml
<?xml version="1.0" encoding="utf-8"?>
<Settings>
  <ShowTrayIcon>True</ShowTrayIcon>
  <UseTransparency>True</UseTransparency>
</Settings>

## Notes

- All option names are case-sensitive and stored as XML element names under `<Settings>`.
- Plugin option domain names correspond to config file names, e.g. `QuickLook.Plugin.ImageViewer` → `QuickLook.Plugin.ImageViewer.config`.
- `LastUpdateTicks` and `TriedUnblock` are internal state values and generally do not need manual editing.
