FAT-formatted drives also let you use space characters in file and folder names. However, other applications may not support these filenames. Windows 95 and Windows 98 maintain two distinct filenames for each file: the filename that you enter in Windows, known as the filename alias, and the filename that is stored on disk, which is DOS-compliant. If a filename you type is DOS-compliant, Windows 95 and Windows 98 save the filename alias as the DOS-compliant filename, but display the filename as lowercase with an initial cap. If a filename you enter in is not DOS-compliant, Windows 95 and Windows 98 create a DOS-compliant filename it uses to store the file on disk that is based on the filename alias. Because Windows may display characters in a filename with a different case than the file's DOS-compliant filename or alias, it is impossible to know whether the file has a DOS-compliant filename by looking at its name in Windows. BIG If a filename alias is altered but not completely retyped, Windows rewrites the assigned alias to match the displayed one. You can view a file's or folder's DOS-compliant name in Windows by right-clicking it and choosing Properties from the pop-up menu. In the Properties dialog displays it as the MS-DOS name. You can also type the dir command at the MS-DOS Prompt to see a file's or folder's DOS-compliant name. Windows not only uses the filename alias for display, but may also use it as a reference when a file is moved, copied, stored, or linked to by an application, server, or other system. Whether Windows uses the alias or the DOS-compliant filename depends on the situation. Windows NT Filenames on FAT-Formatted and NTFS-Formatted Drives Windows NT can read and write to NTFS- and FAT-formatted drives. This is true even if you saved the file with an all-uppercase or a long filename. Filenames saved on NTFS formatted drives can be transferred to Macintosh computers or to servers that supports long filenames with letter case intact. NTFS also generates a valid DOS-compliant filename for backwards compatibility. For example, if you save a file from a NTFS-formatted drive to a FAT-formatted drive, a floppy disk, or to a server that doesn't support long filenames, the DOS-compliant filename is used.
