Therefore, the following method would write to storage/app/example. By default, this value is set to the storage/app directory. When using the local driver, all file operations are relative to the root directory defined in your filesystems configuration file. You may configure as many disks as you like and may even have multiple disks that use the same driver. The local driver interacts with files stored locally on the server running the Laravel application while the s3 driver is used to write to Amazon's S3 cloud storage service. Example configurations for each supported driver are included in the configuration file so you can modify the configuration to reflect your storage preferences and credentials.

Each disk represents a particular storage driver and storage location. Within this file, you may configure all of your filesystem 'disks'. Laravel's filesystem configuration file is located at config/filesystems.php. Even better, it's amazingly simple to switch between these storage options between your local development machine and production server as the API remains the same for each system. Using Dropbox just like any external drive while sharing also the catalog seems a dream today. If you can point to links about cooperation from Dropbox and other Adobe apps, that could help. The Laravel Flysystem integration provides simple drivers for working with local filesystems, SFTP, and Amazon S3. Dropbox integration from syncing does work but does not allow direct referencing of files in the Cloud and is not a solution to too small SSDs.

Laravel provides a powerful filesystem abstraction thanks to the wonderful Flysystem PHP package by Frank de Jonge.
