This is something I'm not too sure about. Personally, I feel that the user should be responsible for updating the file size. Expecially because you may also want to decrease a files size.
When writing, you can update your file size in your loop every maybe 10 sectors or whatever you wish, or before, or after you write data. One other thing to note is that you must write full sectors. So, with the fat32 small lib, you can't write to the exact end of a file, you have to start at the next sector. Adding data to a sector that already has some data would mean that you will need to store the entire sector somewhere. This is another reason why you can only have one file. I also noticed that this fat32 small lib uses a lot of stack on smaller processors like 16f877a. I'm not sure how to reduce that. Matt.
