# Breaking: #65305 - DriverInterface has been extended

See [forge#65305](https://forge.typo3.org/issues/65305)

## Description

The `getFolderInFolder()` and `getFileInFolder()` functions have been added to `DriverInterface`.

## Impact

Any FAL driver extension will stop working due to the change in the interface.

## Affected Installations

Any installation with a custom FAL driver, like WebDAV or Dropbox.

## Migration

The functions `getFolderInFolder()` and `getFileInFolder()` must be added to the custom FAL driver.
A non-hierarchical driver needs to throw a "not implemented" exception when calling these functions.
