8.3 names

8.3 names refer to the short file name format (eight characters, a period, and three characters) used by older MS-DOS and Windows systems for compatibility. On NTFS partitions, Windows automatically generates an 8.3 name for each long file name to support legacy applications. This tag covers discussions about disabling 8.3 name creation on NTFS volumes, often to improve performance or reduce directory enumeration overhead. The primary resource referenced is Microsoft Knowledge Base article 121007, which provides instructions for disabling this feature via the registry or command-line tools like fsutil. Users typically seek to disable 8.3 names on modern systems where legacy compatibility is unnecessary.
