under the topic File system theory
why is this so? can you explain?Because of the limited cluster size, The maximum number of files possible is 4,077
Not quite. 224 is the default size for the root directory but it can be exanded if you need to fit more entries in. The only requirement is that:As a historical side note, when the original FAT12 didn't have directory support, maximum number of files was 224 (field 'root entry count' in bios parameter block) and still is for the root directory.
