# Deprecation: #109409 - Access to arbitrary resources in extensions {#deprecation-109409-1774787352}

See [forge#109409](https://forge.typo3.org/issues/109409)

## Description {#description}

Accessing extension resources outside the configured resource
definitions is deprecated.

By default, extension resources are limited to the following paths:

-   `Configuration`
-   `Resources/Private`
-   `Resources/Public`

If a resource identifier references another extension path, that path
must be configured explicitly in `Configuration/Resources.php`.

See [Feature: #109409 - Allow configuration of resources](https://docs.typo3.org/permalink/changelog:feature-109409-1774770383) for information on how to
configure resources for extensions.

## Impact {#impact}

TYPO3 installations using resource identifiers that reference extension
folders outside `Configuration`,
`Resources/Private`, or `Resources/Public`
will receive a deprecation message when such a resource is resolved.

Every accessed resource must be configured beforehand as described in
[Feature: #109409 - Allow configuration of resources](https://docs.typo3.org/permalink/changelog:feature-109409-1774770383).

## Affected installations {#affected-installations}

TYPO3 installations using resource identifiers that reference extension
folders outside `Configuration`,
`Resources/Private`, or `Resources/Public`.

## Migration {#migration}

Either configure the referenced paths explicitly in
`Configuration/Resources.php`, as described in
[Feature: #109409 - Allow configuration of resources](https://docs.typo3.org/permalink/changelog:feature-109409-1774770383), or move the resources to a path that
is already configured.
