Hey sunderam1996-
The download process shouldn’t delete/remove any files that were already downloaded when it was paused. When I tested locally, I was able to pause/resume the download at the same point it left off. If the percentage is showing at 0% when you restart, it is likely trying to validate/verify the downloaded files in order to pick up where it left off. If this is not what you’re experiencing, can you explain exactly what you’re seeing on your end and what you mean when you say the data was lost?
