GetFileSystem(?string $uri = null): ?Filesystem Get the file system object. The argument is the URI (used by PHPMaker) of the bucket or container, e.g. "s3://my-bucket", "google.storage://my-bucket", "azure.blob://my-container". Then you can use the ``$filesystem`` with [Filesystem API](https://flysystem.thephpleague.com/docs/usage/filesystem-api/) directly.

ReadFile(string $path, Filesystem|string|null $fileSystem = null): string Read a file by path relative to the root of the file system. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute.

WriteFile(string $path, string $data, array $config = [], Filesystem|string|null $fileSystem = null): bool Write a file by path relative to the root of the file system. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute. The ``$config`` depends on file system adapter. **Note** When writing files, the directory you're writing to will be created automatically if and when that is required in the filesystem. If your filesystem does not require directories to exist (like AWS S3), the directory is NOT created. Of course, you can always create the directory yourself.

DeleteFile(string $path, Filesystem|string|null $fileSystem = null): bool Delete a file by path relative to the root of the file system. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute.

DeleteDirectory(string $path, Filesystem|string|null $fileSystem = null): bool Delete a directory by path relative to the root of the file system. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute.

ListContents(string $path, bool $recursive, Filesystem|string|null $fileSystem = null): DirectoryListing List directory contents. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute.

FileExists(string $path, Filesystem|string|null $fileSystem = null): bool Check if a file exists. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute.

DirectoryExists(string $path, Filesystem|string|null $fileSystem = null): bool Check if a directory exists. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute.

CreateDirectory(string $path, array $config = [], Filesystem|string|null $fileSystem = null): bool Create a directory. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute. The ``$config`` depends on file system adapter.

MoveFile(string $sourcePath, string $destinationPath, array $config = [], Filesystem|string|null $fileSystem = null): bool Move a file. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute. The ``$config`` depends on file system adapter.

CopyFile(string $sourcePath, string $destinationPath, array $config = [], Filesystem|string|null $fileSystem = null): bool Copy a file. If ``$fileSystem`` is not specified and is not local, the ``$path`` must be absolute. The ``$config`` depends on file system adapter.
