Upload File Progress

how to get the percentage of file uploading? Does the Storage API provided a data of total percentage of file uploading, so that I can use this on my client side.

TL;DR

The user is concerned that the progress is only shown every 5MB, making it inaccurate. They are asking if there is a way to get the percentage of file uploading and if the Storage API provides this data. The solution is to use the callback parameter for the create file function. The Storage API uploads files in 5MB chunks. To get the percentage of file uploading, you can calculate it based on the size of each chunk uploaded.
