# Why does my Catalog take so much space?

The most common reason is the **Cache Documents** folder on Windows / **History** folder on macOS, where your edits are located (the history of edits, including sky textures that were applied to the pictures, erased layers, the applied LUTs, masking, etc.). The logic is simple: the more images you adjust, the more space is taken by the Cache Documents (on Windows) / History (on macOS) folder.

These files are **automatically removed** when you remove the associated images from your Luminar Neo Catalog.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.skylum.com/why-does-my-catalog-take-so-much-space.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
