But if it hasn’t been too long since you deleted the file, the chances of complete recovery are pretty good! No Data Recovery software is perfect: if a file has been partially/wholly overwritten or otherwise compromised, recovery chances are low. While deleted files are inaccessible and are in danger of being overwritten, they can often be recovered with professional data recovery tools. In layman’s term, data recovery software scours the hard drive to look for the pages marked with 0’s to locate any recoverable data, piecing it back together and providing it in a salvageable format. So now, how does the recovery software work? In course of time, the data in this space can be overwritten by other files, and thus compromising the original file that you had you deleted and intend to recover. The deleted data is still there, but you have indicated that you are not concerned about it, since you have deleted it. The file never gets deleted, but what happens is that the pages of the book which contain the data of the file are now marked with a 0, thus designating the space that the file is using as being available for future use when needed. Makes sense, right?įirstly, let us understand what happens when you delete a file. The net ‘ free capacity‘ of your hard drive is empty is the sum of the block sizes of the pages which are marked as 0 (empty). Now consider a flag – 0 or 1, indicating whether a page of the book is empty or is occupied by some text. Naturally, your data would be the text contained in the pages of the book. Lets use the analogy that your device is a book, and the blocks of the hard disk/SSD are the the pages of the book.
