after i change computer,i copy all the file of folder,but the data(all cards drops and the time of use) still lost

They aren't lost, they were "picked up" and they went to your inventory, then the program refreshes the amount of cards that still need to pick up and just goes on from that.

If you close at 4 cards of 10 and then reopen it starts at 0 of 6
