# Deprecation: #93944 - File Tree as iframe migrated to SVG-based tree {#deprecation-93944}

See [forge#93944](https://forge.typo3.org/issues/93944)

## Description {#description}

When registered backend modules have the legacy-tree navigation frame
`file_navframe` set via the module configuration
`navigationFrameModule`, the modules are now using the new SVG-based Folder
tree view as component (non-iFrame).

## Impact {#impact}

Modules still registering the old `file_navframe` option via
Module Configuration `navigationFrameModule` will automatically be migrated
to the new Component, and a PHP `E_USER_DEPRECATED` error will be triggered.

## Affected Installations {#affected-installations}

TYPO3 installations with custom extensions having backend modules
using the filelist navigation frame (folder-based tree).

Modules that use the implicit main module configuration and are
located directly within the "File" module are not affected.

## Migration {#migration}

Change the affected code in your ext_tables.php:

`'navigationFrameModule' => 'file_navframe'`

to

`'navigationComponentId' => 'TYPO3/CMS/Backend/Tree/FileStorageTreeContainer'`
