Fixed ! It reads from the headers of URL itself , it will be not instant, may lag of couple of mili seconds but it will require some UI changes later on ! Will solve the problem for now ! When working on refactoring , database scheme should be changed and it should store file size as array for hdx exports [ ] and display from table instead of reading from URL , will reduce the network traffic . cc: @ramyaragupathy
