#=1) By default, 'last-accessed' timestamp of a file when that file is opened. Because updating the last-accessed timestamp requires writing data to the disk, an activity that accesses many files might be faster if this type of update is disabled.
#=\n\n2) Determines whether NTFS generates a short name in the 8.3 naming convention for long file names. If this is enabled (default), files can have two names: the name that the user specifies and the short name that NTFS generates. If the name the user specifies conforms to the 8.3 naming convention, NTFS does not generate a short name. Although disabling this setting increases file performance, some legacy 16-bit applications that cannot process long file names might not be able to find the files.
#=\n\n3) On NTFS volumes, file names using the 8.3 naming convention are limited to the standard ASCII character set by default. If "Allow extended characters in 8+3 filenames" is activated, Windows can use extended characters for 8.3 filename creation. Enabling this option might lead to problems with some legacy 16-bit applications.
