Post subject: how to see which sector belongs to which file in fat32? Archived from groups: microsoft>public>win98>fat32 (more info?)
i know it's written somewhere in FAT (1. sector and size of file) but
i don't know how to read it in my application? i can access drive on a
raw-data level and print out all of the sectors, but i'd like to look
which sectors are free and which are used by which files. how do i do
that? vc++ 6.0 is the language

The size of the file is not part of the FAT. The directory entry contains a
pointer to the first sector. The FAT entry for this first sector contains
the sector number of the second sector, and so on until the FAT entry
contains the indicator for no more sectors.

Yes - cluster. I'm sure OP can make the translation.

The file size is not stored in the FAT, but it is stored in the file's
directory entry.
