1. How about removing useless files that generated automatically, like weather, counter.

2. When dealing with cross-language calls, we have to be careful with large binary arrays. Some unnecessary data transfers will affect performance. In image decoding, we get binary to dotNet, send back to js, then wrap as Blob, then unwrap Blob in our SDK inner logic...this is expensive. We can let js can get inputElement by id or className, inputElement.files to get blobs.
