Невозможно записать операцию расход

При попытке ввода расхода получаю ошибку

Ошибка: Could not allocate space for object 'dbo.Operations'.'PK_Operations0' in database 'homemoney' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.
