How Data Recovery Software Works: The Science Behind Restoring Lost Files

In an era where everything important is done on computers, we have all become dependent on one simple command: "Ctrl+S". Live by these keys or suffer the consequences. Losing a single document could jeopardize your GPA in school or even a job position, and losing photos or videos could cause precious keepsakes to vanish in an instant. Keeping your data accessible at all times is essential to getting things done these days, but sometimes, remembering to save isn't enough. Computer crashes, hardware glitches, software bugs, and ransomware attacks can corrupt your files, making them inaccessible. We know how frustrating this can be. Fortunately, Stellar Data Recovery Professional Software can bring lost data back from the dead.

This software restores deleted files with a simple, user-friendly interface. It's a program for Windows- and Mac-based storage devices that can recover lost data from hard disk drives (HDDs) and solid-state drives (SSDs), as well as portable storage devices like external drives, SD cards, and USB drives. Backed by 30 years of experience and certified by the ISO, Stellar's software is straightforward and multifaceted. Here's how it works.

How Stellar Data Recovery Professional works

When you delete a file, its contents don't actually get erased — not immediately, at least. The action of deleting a computer file frees up whatever storage space the file had been using, but until something actually overwrites that file, all the information it contained still technically exists within your computer storage (or external drive). However, deleting a file does unlabel it, making it impossible to find by normal file-browsing methods.

Fortunately, Stellar Data Recovery Professional can get around that problem. It scans your drive for data from deleted files and recovers whatever hasn't been overwritten yet. You can scan for specific files or file types (such as videos or photos) or complete a deep sweep of your computer to recover every lost bit of data — even things you might have forgotten about. You can even preview and recover files during the process, so you don't have to wait until the whole scan is complete to start getting your stuff back.

Stellar can recover lost data from numerous different storage devices, not just hard drives. If you have CDs, DVDs, or Blu-ray discs that have become scratched and unreadable, Stellar can scan them and recover the content. If you realize you accidentally deleted an important email, you can get it back, too, since Stellar can recover files from Microsoft Outlook, Outlook Express, Exchange Server, and other options. It can even recover files that have been encrypted using BitLocker.

Recover memories that matter with Stellar Data Recovery Professional

Stellar Data Recovery Professional can recover practically any type of file. For documents, it supports Microsoft Word documents, PowerPoint presentations, Excel spreadsheets, Google Docs, and more. For photo file types, it supports JPEG, TIF, PNG, and more; for video file types, it supports AVI, MPEG, and M4V, among others; and for music file types, it supports WAV, MP3, M4A, and many more. The software includes recovery for documents, photos, videos, music, emails, and archive data, and it supports encrypted data recovery and recovery from lost partitions. 

Stellar offers multiple plans to suit your needs. Its most popular Stellar Data Recovery Professional recovers and restores deleted, encrypted, or corrupted files, photos, documents and more, even from completely crashed and unbootable operating systems. This package also offers a convenient "pause and resume scan" feature, so you don't have to complete your tasks in one sitting. Stellar's "Premium" package includes some additional features, like the world's first Windows data recovery software to recover and repair photos and videos. Stellar's most advanced "Toolkit" option provides even more capabilities, including RAID/NAS support.

Just to be sure it really works for you, customers can even download a free trial of each Stellar software program, which will scan your computer and tell you if there's anything to recover.
