I would like to save one text file on a limited memory mass storage (~22kB). The problem is that the file system header size is too big for this application. The standard FAT32 header takes ~20kB of memory. In case of FAT12 it is only ~10kB, but that is too much for my application, I need to reduce the header size as much as possible because I need more space for the data stored in the file.

I would like to ask if there is any file system that requires less space for the header, or is it possible to reduce the FATFS header size (for example, not storing date or name information)?
