Question

I’m developing an app that will download large files (mostly videos). What I need to know is this:

1. Is there a max singe file size imposed by either Android or iOS? All I’ve seen is the 4GB limit of a FAT filesystem. The max video size should come no where near that, but we want to be 100% sure that there isn’t a lower limit
2. Is there a max amount of space allocated to a single app on either system? Google turned up nothing on this question, so I am going to assume there isn’t a limit beyond available file space (which seems logical, but also far to free for an Apple-built system)
3. Is there a max number of individual files or directories for either system? Again, Google turned up nothing. I don’t see why there would be here, but I want to cover all the bases here.

Thanks!

Answer 1

All answers here are for Android:

Is there a max singe file size imposed by either Android or iOS? All I’ve seen is the 4GB limit of a FAT filesystem.

I would not exceed 4GB.

Is there a max amount of space allocated to a single app on either system?

No, there is no per-app quota system at this time. That being said, try not to make users regret using your app. 🙂

Is there a max number of individual files or directories for either system?

Yes, but since the counts should be in the millions, your app will grind to a halt long before you hit those limits.
