#111627 - file length -> change in FAT
Responding to: ???'s previous message
Andy Neil said:
For a little extra work (though still less than a full FAT implementation), could you set the length in the file's directory entry? (I'm speculating here)


Besides changing file length in directory entry you need also mark the end of cluster chain in FAT. Although the PC OS's (let me not name all of them which "know" FAT) might generally survive an inconsistency if you omit one of the two, it is certainly not a practice the "Old Boys Club"(*) would recommend.

Being able to change directory entries and FAT entries is quite close to a reasonably full implementation... :-)
