From resource kits:

A FAT32 volume must have a minimum of 65,527 clusters. Windows XP Professional can format FAT32 volumes up to 32 GB, but it can mount larger FAT32 volumes created by other operating systems.

Description                        Limit
Maximum file size             4 GB minus 1 byte (232 bytes minus 1 byte)
Maximum volume size       32 GB (implementation)
Files per volume               4,177,920

Maximum number of files and subfolders within a single folder 65,534 (The use of long file names can significantly reduce the number of available files and subfolders within a folder.

Some more info @
(the Fat-32 file system has a maximum accessible limit of 2.2 terabytes)

I already know this information. The last part of your answer is my question. How many files can I have in a directory?. Lets say if I have 128 charecters filename files, How many files can I have in one directory?

Ok i found out that using long file names reduces the limit of files to 16,383 (2^14).
