# Variables

## Introduction

Variables are used in Couchdrop to support custom filename and path creation in automations. Whenever setting a location or path in an automation, you can use variables to generate an appropriate path.

## Available Variables

The following variables are available for automations

<table><thead><tr><th width="262.88671875">Key</th><th width="187.765625">Value Example</th><th>Description</th></tr></thead><tbody><tr><td>{USER}</td><td>michael.lawson</td><td>The user who was uploading the file</td></tr><tr><td>{EXISTING_NAME}</td><td>test.txt</td><td>The current filename</td></tr><tr><td>{EXISTING_NAME_NOEXT}</td><td>test</td><td>The current filename without the extension</td></tr><tr><td>{EXISTING_NAME_EXT}</td><td>.txt</td><td>The extension only of the current filename</td></tr><tr><td>{YYYY}</td><td>2023</td><td>The current timestamp year</td></tr><tr><td>{YY}</td><td>23</td><td>The current timestamp year in shortform</td></tr><tr><td>{MMM}</td><td>AUG</td><td>The month in a human readable format</td></tr><tr><td>{MM}</td><td>03</td><td>The month in a numerical format</td></tr><tr><td>{DD}</td><td>02</td><td>The day of the month</td></tr><tr><td>{TIME_HH}</td><td>23</td><td>Hour in 24 hour time</td></tr><tr><td>{TIME_MM}</td><td>30</td><td>Minutes of the hour</td></tr><tr><td>{TIME_SS}</td><td>24</td><td>Seconds on the minute</td></tr><tr><td>{TIMESTAMP}</td><td>1711330141</td><td>Unix timestamp.
