### What should this feature add?

Some background: when downloading a large model, the download kept failing about half way through. I presumed it was a networking error or something, and retried the download. It wasn't until I looked at the console that I realized that I was out of disk space.

Suggestion: Trap file system errors for downloads or file creation/deletion, and inform the user why the operation failed in the web UI's error toasts. Currently it just says it failed with no explanation.

### Alternatives

There's always the console, of course. But I often use Invoke on a less powerful touchscreen device.
