# Regex folder name filter

Regular expressions  (shortened as **regex** or **regexp**) are patterns used to match character combinations in strings.

![](/files/862DPOGfyG4e88x2MpoT)

To use regex filter enclose search pattern in slashes: "/temp/, "/\d/".

For example you have folders generated by Media Encoder, it takes project name and attaches "\_AME" to the end of it:

> **"Project\_1\_AME", "Project\_2\_AME", "Project\_3\_AME", etc**

Instead of strictly defining name filter for each folder, you can set one regex filter:

> **"/\_AME/"**

### Example usage:

* **/\_ame/** — filter folder that has “\_ame” in name: “project\_ame”, “south\_America”, “\_amethyst"
* **/\_ame$/** — filter folder that has “\_ame” at the end of the name:  “project\_AME”
* **/^\_ame/** —filter folder that has “\_ame at the start if the name: “\_amethyst"
* **/\d/** — filter folder that has any digit in name: “100\_images”, “image\_5\_best”

## 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://manuscript.knightsoftheeditingtable.com/extensions/watchtower/settings/regex-folder-name-filter.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.
