The FAT directory entry contains the name and metadata for a file or directory. One of these entries is allocated for every file and directory, and they are located in the clusters allocated to the file’s parent directory.
This data structure supports a name that has only 8 characters in the name and 3 characters in the extension.
If the file has a more complex name, there will be a long file name directory entry in addition to a directory entry.
- The long file name version is discussed in the next section of this article.
