Answers
your OS never delete you file permanently by default it store in the HDD but remove the location pointer of that file from users (if your are programmer or CS person then you can understand it by the concept of encapsulation, hiding thing from the end users. Actually OS only rewrite a particular file to delete it permanently i.e when you have deleted a file it go to garbage collector then when you want to copy a thing like movie or songs to your computer, then computer see the vacant space in your HDD which is the garbage collector space it then pick a particular address and write it to the HDD and OS also put that address to the file system so that it is visible to the end user. So when this process is completed then the garbage or free space in which this new file is written the file which is in that garbage or free space is deleted permanently now.
