Each cluster contains a pointer to the next cluster in the file, or an end-of-file indicator at 0xFFFF , which indicates that this cluster is the end of the file.
The diagram shows three files: File1. In each case, the file allocation table entry points to the first cluster of the file. FAT16 has undergone a number of minor modifications over the years, for example, enabling it to handle file names longer than the original limitation of 8. The latter is little more than an extension of the original FAT16 file system that provides for a much larger number of clusters per partition.
The FAT file system is characterized by the file allocation table FAT , which is really a table that resides at the very "top" of the volume. To protect the volume, two copies of the FAT are kept in case one becomes damaged. In addition, the FAT tables and the root directory must be stored in a fixed location so that the system's boot files can be correctly located.
A disk formatted with FAT is allocated in clusters, whose size is determined by the size of the volume. When a file is created, an entry is created in the directory and the first cluster number containing data is established. This entry in the FAT table either indicates that this is the last cluster of the file, or points to the next cluster. Updating the FAT table is very important as well as time consuming.
If the FAT table is not regularly updated, it can lead to data loss. It is time consuming because the disk read heads must be repositioned to the drive's logical track zero each time the FAT table is updated.
There is no organization to the FAT directory structure, and files are given the first open location on the drive. In addition, FAT supports only read-only, hidden, system, and archive file attributes. FAT uses the traditional 8. The name of a file or directory can be up to eight characters long, then a period. The name must start with either a letter or number and can contain any characters except for the following:. If any of these characters are used, unexpected results may occur.
The name cannot contain any spaces. It is not possible to perform an undelete under Windows NT on any of the supported file systems. Undelete utilities try to directly access the hardware, which cannot be done under Windows NT. For further discussion of FAT advantages, see the following:.
