File Manager
Please don`t worry, follow these steps for a try:
1. Enter vivoCloud, Google drive or other cloud drive apps you frequently use to check if the files has been backed up;
2. If the files you delete are the pictures or screen recordings, please go to Settings>Albums to check if Recently deleted is turned on. If yes, go to Albums>open Recently deleted to check if the files are available;
3. If the files are saved in SD card, you can Google some apps which might help recover the data from SD card.
Hope that helps.
