SYMPTOMS
When you install Microsoft Train Simulator on your computer, a complete installation may require a greater amount of disk space than the disk-space requirements listed on the box for a full install.



CAUSE
A complete installation of Train Simulator requires about 1.8 gigabytes (GB) of disk space (not including the swap file) unless you install the program to a FAT16 volume. If you install to a Fat16 volume, the installation may require as much as 2.2 GB because of the cluster size of a FAT16 volume. On a hard disk that uses the FAT16 file system, the smallest amount of space that a file can use is equal to the size of one cluster. This means that a 1-kilobyte (KB) file stored on the hard disk may actually use up to 32 KB of physical disk space, rather than 1 KB of disk space. Train Simulator installs a large number of small files (1 to 2 KB), including images (JPG).

Note This behavior does not occur on a FAT32 file system or on NTFS file systems, because these systems do not have a 32-KB limitation.



MORE INFORMATION
Windows 95 Gold only supports FAT16 volumes, but Windows 95 OSR2, all versions of Windows 98, Windows ME and Windows 2000 can support FAT32.

It may be possible to use Microsoft utilities to convert a FAT16 volume to FAT32 in some operating systems. More information including information on who to contact for support of these tools can be found in the following articles:  Window98, Windows Millennium
