Why are file names in Bangle.js limited to 28 chars? #7826

The title pretty much says it all, just curious why... 28 seems like an odd number to limit chars for filenames |

We want to try and keep things aligned on at least 8 byte boundaries (some STM32s have a restriction iirc), and so it made sense to make the file header 32 bytes. We pack the file size and other flags into 4 bytes, and that leaves 28 for the name :) Originally it was 12 characters I think and a 16 byte header, but I expanded it. |
