I connected my phone (Redmi 1S) to my PC (Windows 7 64-Bit) as media device to view and copy files from PC to phone's internal storage. I saw some unwanted files & folder are present in storage and decided to delete them. i deleted some junk folders and disconnected my phone from PC. After that i opened gallery to see i recently transfered photos from PC. I just felt shocked to see that the gallery is showing photos only present in SD Card and my internal storage is empty. I opened file manager to check files and there is only pre defined folders are only present like Android, DCIM remaining files and folders are just gone. i don't know what happened. Please help me guys what just happened? and How the files are gone?
