The same way as with any other (non-root) directory or file.
Follow the cluster chain starting at BPB_RootClus (I'm assuming you have fatgen103.doc).

no....
I just want loop over all entries and print the files name
so i need to know how many entries there is in the disk

The only way to tell how many entries is to read the entire root directory and count them.

What my friends are saying is that FAT32 does not have a fixed root directory like FAT12 and FAT16 do. The FAT32 root directory is just like a sub-directory, it has Allocation Units and can be of any size up to the disk size (in theory).
