Lost my videos

Solution
In an Android device, go to the Play Store and download Root File Manager. It gives you better file management than the stock utility and you don't have to root the phone to use it.

Install it and look in the System folder for LOST.dir then see if there are any files in there. It's Android's equivalent to Windows' Recycle Bin so if you find some files, copy them into a new folder RFM lets you create.
