# Run folder sizes and Disk Space on the MiSeq

All run folder sizes listed below should be used only as an approximation.

* Folder size will vary depending on the raw cluster density and the number of clusters passing filter for the run.
* The examples below are based on dual-indexing runs with optimal clustering and clusters passing filter greater than 80%. The following also include FASTQ files generated on the instrument by MiSeq Reporter or Local Run Manager.

**Notes:**

* The MiSeq hard drive is 700 GB total.
* 141 GB are partitioned to C:\ for Operating System Files and Illumina Software Installation.
* The remaining 559 GB are allocated for D:, where run data is stored, the following way:

# Agent Instructions: 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:

```
GET https://knowledge.illumina.com/instrumentation/miseq/instrumentation-miseq-reference_material-list/000006711.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
