1.4.2 Long File Names

Long file names are UNICODE4 names that can be up to 819 characters per name. To achieve this, the names are split up into 32 byte fragments that fit into directory entries, and placed in the directory in reverse order with the associated file entry immediately following.

Long file name fragments can be identified by the attributes field, which will have the Read-Only, Hidden, System, and Volume flags set.
