This was a joke? Uncompressing 800kb file isn't a matter of milliseconds on low-end SimCoupe machines (200MHz CPU). And seeking = uncompressing, so I suppose you would rather directly uncompress it to a memory buffer, and then read it from that buffer. > Or to test for a specific size just seek to it and make sure you can't > read 1 byte more.

Seeking in compressed stream is something ***consored***. > Si Aley
