# Advanced configuration
Advanced configuration provides power-user access to The Wallet Crew tenant YAML configuration. Each tenant has a set of YAML files that define its complete configuration.
Secrets are not stored in these files. The Wallet Crew stores secrets in a dedicated Key Vault.
The **Advanced configuration** editor is intended for power users. It provides controlled access for support-directed exceptions, full configuration backups, imports, and change review.
{% hint style="warning" %}
Do not use this editor unless The Wallet Crew Support team asks for a specific change. Most settings have dedicated screens that update the underlying files safely.
{% endhint %}
Real-world examples
* The Wallet Crew Support team provides a configuration adjustment for an exceptional connector requirement.
* A power user exports an `.fctwc` backup before a support-guided configuration update.
* A team compares staging and production configuration before an approved release.
### Open the advanced configuration editor
Open the tenant's advanced configuration editor from **Settings** → **Advanced configuration**.
Use the editor only after receiving instructions from The Wallet Crew Support team. Do not change a configuration file without those instructions. A file can affect several platform features.
### Export or import a full tenant configuration
The editor can export the full tenant configuration as a backup. The exported file uses the `.fctwc` extension, which means **Full Configuration The Wallet Crew**.
An `.fctwc` file is a ZIP archive containing all tenant configuration files. Keep exports securely, as they can contain configuration details.
Use import to restore or transfer a previously exported tenant configuration:
1. Export the current configuration before making changes.
2. Select the `.fctwc` file to import.
3. Review the imported configuration, then validate its effect in the relevant administration screens.
{% hint style="info" %}
An import restores configuration files only. Secrets remain managed separately in the dedicated Key Vault.
{% endhint %}
### Review tenant configuration changes
The configuration audit history records tenant configuration changes. Open **Settings** → **Monitoring** → **Audit** to review them.
The history table shows four columns:
* **Timestamp** — when the change occurred.
* **File name** — the configuration file that changed.
* **Author** — the person who made the change.
* **File changes** — the recorded modification.
Each entry provides two comparison actions:
* **Compare with previous** shows the selected version against its preceding version.
* **Compare with current** shows the selected version against the active configuration.
### Compare tenant configurations
Open **Settings** → **Tools** → **Configuration comparison** to compare tenant configurations without changing them.
This view can compare configurations across environments. It can also compare tenants when access includes more than one tenant. Select a date to compare the active configuration with a previous version.
Use comparisons before importing a backup or applying an exceptional manual change. This helps identify unintended differences early.
### Configuration file reference
Each configuration file has a dedicated reference page. These pages describe the file's purpose, supported YAML schema, and configuration constraints.
### FAQ
When should the advanced configuration editor be used?
Use it only when The Wallet Crew Support team requests a specific change. Standard platform features should be configured through their dedicated administration screens.
Does a full configuration export include secrets?
No. Secrets are stored separately in the dedicated Key Vault and are not included in `.fctwc` exports.
Can configurations be compared across tenants?
Yes, when the account has access to more than one tenant. The comparison view also supports environment and date-based comparisons.

## 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://docs.thewalletcrew.io/configure/advanced-configuration/advanced-configuration.md?ask=&goal=
```
`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.
