Delete the back and get it all says Sinhala video

You see, when you delete a file on Windows, the file isn’t actually gone; just the pointer that tells Windows how to find it. The data is left intact, and the space is marked as “empty” and to be overwritten in the future. Here’s the tricky bit: as Windows randomly writes to the disk, it could overwrite a portion of your deleted file, corrupting your data. So you want nothing writing to your disk at all. Browsing a website will write to your disk. Playing a song may very well do it, as Windows remembers your most recent documents. - See more at: http://www.sirilankawa.org/2016/09/delete-back-and-get-it-all-says-sinhala.html#sthash.83XOuIoE.dpuf
