In the world of computers and technology, security is the major issue and hence all the operating systems bring this issue into limelight by adopting various methods and types of conventions like the File names too long. There are many sort and long filenames given to the document but the basic character strength will increase only if the naming scheme is alike the Microsoft DOS in regards to other filenames like the FAT and the NTFS file systems. Filenames should never be too long and if they are long enough then they are evry descriptive, extending the characters from 8.3 filename. If the characters in filenames included are long then the extensions used in the operating system can be of an advantage like the .jpeg, .tiff,.xhtml,.html. Windows NT 3.5 was the 1st operating system to implement the system of long filenames on the FAT. There is the maximum character strength of 255 in the system of 255 characters which will include the non-alphanumeric characters and the spaces and this will include the special character like: \ / : * ? ” < > |. This system will be achieved by 13 2-byte Unicode characters by forming chain of 20 13 2-byte files.
Compatibility with the File names too long
A method of generating 8.3 filename by the long filename was formulated by the Microsoft and it was just to maintain the compatibility with the older operating system versions. For example: Microsoft.txt will be compatible with the MICROS~1.TXT for easy file association. LFNs were included in the operating systems FAT by the Microsoft Company. In their too long filename the characters were hidden with the volume label and stronger filenames. It was the scheme best for compatibility because the volume labels are generally ignored by the operating system components and programs. The programs with short filenames are easily accessed with codes on them when the new LFN operating system will use the longer filenames.
Easy to decode filenames
Initially the File names too long were introduced by the operating system and there were some problems earlier like the directory level operations with the DOS mode will easily destroy the long filename details by default and this will sector level hard disk which allowed in the default mode. There is requirement of the LFN drivers to be installed initially if the long filenames booting is done in simple plain OS. Not many of the LFN support programs were added to the earlier programs. This included the Windows for Workgroups, File Manager and it was obsolete with the new operating system components like the Explorer and the Shell. There will be file system beginning with NT 3.1 release and supported by the NTFS over the LFNs systems. There were many utilities required to update this File Manager and this was updated to support the Windows 95. It was initially that the Workgroup Windows 3.11came from LFN support and FAT for Windows 95 preparation.
Due to the File names too long the maximum length of the filename will reduce depending on the deep hierarchy of the root folder.
