For most documents, this is plenty. However, 1MB is too small for a useful file storage. For this reason, LiteDB implements FileStorage, a custom collection to store files and streams.** - FileStorage uses two special collections: The first collection stores file references and metadata only (by default it is called _files) ... The second collection stores binary data in 255kB chunks (by default it is called _chunks) - The FileStorage collection contains simple methods like: Upload: Send file or stream to database. Can be used with file or Stream. If file already exists, file content is overwritten. Download: Get your file from database and copy to Stream parameter Delete: Delete a file reference and all data chunks Find: Find one or many files in _files collection. Returns LiteFileInfo class, that can be download data after. SetMetadata: Update stored file metadata. This method doesn’t change the value of the stored file. It updates the value of _files.metadata. OpenRead: Find file by _id and returns a LiteFileStream to read file content as stream
