# Folders {#architecture-folders}

The actual storage structure depends on which
[driver](https://docs.typo3.org/permalink/t3coreapi:fal-architecture-components-drivers@main) each
[storage](https://docs.typo3.org/permalink/t3coreapi:fal-architecture-components-storage@main)
is based on. When using the local file system driver provided by
the TYPO3 Core, a storage will correspond to some existing
folder on the local storage system (for example, on the hard drive). Other
drivers may use virtual structures.

By default, a storage pointing to the `fileadmin/` folder
is created automatically in every TYPO3 installation.

## Processed files {#fal-architecture-folders-processed-files}

Inside each storage there will be a folder named `_processed_/`
which contains all resized images, be they rendered in the frontend
or thumbnails from the backend. The name of this folder is not
hard-coded. It can be defined as a property of the storage.
It may even point to a different storage.
