28. Allocating A New File

1. Find first free entry in directory and write file name

2. Search FAT for unallocated cluster; set to EOF (0xFFF)

3. Write that cluster's address into directory entry

4. If another cluster is needed,

   • find an unallocated FAT entry,

   • reset that value to EOF, and

   • reset previous FAT pointer to this new cluster

   (Repeat this step as necessary.)
