Internal storage has been wiped out in blink of an eye 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 &amp; 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?
You've most likely deleted the storage folder seen in the PC view.

This folder isn't necessarily present in the root of your internal storage, it's more like a link to your whole internal storage. I don't know about how it's generated, but since Windows disrespect links, deleting it is effectively wiping the internal storage itself. I had this happened to me on my own Nexus 4, and restoring data was a painful process, and in most senses failed - most of my music files are only available as 8MB fragments, and pictures are distorted or simply unreadable.

Do check out the data-recovery tag wiki for tips on attempting to restore it, but as I said, don't get hopes up on restoring data in one piece.
