So if I understand this correctly, a PC-mirror means that both the Atari or the PC, can write to, copy, or move files that are stored in a PC folder? If this is correct, then this would be the ultimate way to handle things, since I presume that the PC (Windows, Linux, or MAC) could use its built-in explorer to manipulate files.
That's the idea, but in practice it's quite complicated to handle writes from the A8 end of things. DOS 2.5, MyDOS, etc, use quite predictable sector write strategies, so it's possible for APE to intuit a sector write's intended purpose and react accordingly. Quite a lot of people are using SpartaDOS X nowadays, however, and access DOS 2.x and MyDOS volumes via the ATARIDOS.SYS driver. Now, SDX doesn't write sectors in quite such a predictable fashion (since it employs an efficient caching system), even when writing to older file systems. If the directory, for example, happened to be modified last (after the last data sector of a file was written), it would be challenging to interpret the data stream as the creation of a new file.
I suspect a nice arrangement down the line would be raw r/w access to a 32MB FAT volume on the PC, using a file system driver on the A8. SDX already has a read-only FAT16 driver, and once that has write capability, read/write transfers between the PC and the Atari will be quite simple.
