Possible issues with large(ish) files [Resolved]

The ?[255] error comes when you had code saved to flash which you were executing from, and then you erase the flash memory while you're still executing that code :) If, after an eraseAll, you do reset() or load() everything will be fine.

I think I should probably just get rid of the 'My Files' tab now since the IDE handles it in a more sane way (and allows you to download StorageFile files directly). Do you have any objections to that?

In terms of file size, I believe each 'chunk' is about 4k, and you get around 255 chunks - so you can save about one megabyte of data. Right now only the first megabyte of flash is actually exposed to JS apps, so that's really all you can store.

1MB of data is a lot though - it'll take ages to download. Do you really need to store data at that granularity?
