Did you accidentally delete a file on your computer, delete a file from your disk, or even format a memory card? Or maybe you can’t find your music collection after a system crash or malware infection on your hard drive? Fortunately, lost files and folders can often be recovered using data recovery software. But how does data recovery software work?
Deleted Data lasts for many years
When you delete a file on your computer, the first place it sends to is in the trash. Emptying the recycle bin makes the file much less accessible, but does not delete it. What happens behind the scenes when you “delete” a file is that the computer’s file system deletes the path to access this file and indicates the space that the file uses as “ unused,” which becomes available for future use when necessary. The ones and zeros that make up the file are still present on your computer until another file overwrites them. Parts of the data can remain on the hard drive for many years, while other components replaced for several hours.
Can you bring back the book when destroyed
One way to visualize this situation is to use a book representing a file. Suppose you decide you don’t want the book anymore, so you put it in the basket to donate to the paper recycling company. When you first “delete” a book (throw it in the basket), it remains intact and easily returns simply by pulling it out of the basket. When the processing company picks up a bunch of your books (emptying the basket), they tear off the cover of the book and put the pages of the book in a pile of other paper to be recycled. The text and pages of the book (the contents of your file) still exist, but without a cover and it becomes much harder to find, and in this collection of paper, you can lose a page or two. As more paper appears at the recycling plant, they destroy the book, to leave more room for others. After the pages destroyed, it becomes impossible to restore them, but up to this point, there is still the opportunity to return the book; it just takes a lot of work.
By analogy, data recovery software greatly simplifies the sifting of piles of paper to find the pages of your book. This process requires special tools and time, but in the end, it is worth it if you need to return this book for some reason.
How data recovery tool search data
Thus, although deleted files are not available and overwritten, you can completely recover them using professional data recovery tools. Data recovery software is designed to search for any recoverable data, assemble it, and present it in a finished form. The best data recovery applications provide a preview of recovered files, filtering and search results, easy file recovery, and additional tools.
What type of data tools can recover
File recovery applications can be used to recover files of any kind or size, from images, music, and videos to documents and spreadsheets. Data recovery software can find and recover emails, executable files, and compressed files. The best file recovery software may even support organizing your file folders and can restore a full partition or disk.
Of course, data recovery software is not ideal; if the file has been partially overwritten or otherwise compromised, the likelihood of any useful recovery is very low, even with the best recovery software. But if you accidentally deleted a file, you noticed it right away, and you didn’t use the disc to record, the chances of a full recovery are pretty good.
