The actual storage structure depends on which Driver each storage is based on. When using the local file system Driver provided by the TYPO3 CMS Core, a storage will correspond to some existing folder on the local storage system (e.g. hard drive). Other Drivers may use virtual structures.

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

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.
