Final Answer:
Files ending with a period (". ") could result from errors during file naming or might be artifacts of system glitches. In most cases, these files serve no intended purpose and are often considered erroneous or remnants of incomplete file operations.
Step-by-step explanation:
Files ending with a period might occur due to various reasons such as accidental keystrokes during file naming, issues with file extensions, or system errors. The presence of a period without any accompanying file extension might render the file unusable or unrecognized by standard software applications.
Such files can be remnants of system glitches, naming conventions, or formatting errors, lacking a proper file extension necessary for the system to identify and associate the file with a specific application or file type. In practical use, these files typically hold no functionality or intended purpose and may require correction or deletion to avoid confusion or clutter within file systems.
