6 Best Open Source Data Recovery Software Solutions

6 min read

Reading Time: 6 minutesMost data recovery programs have a free trial, but ultimately you do need to pay if you want to recover a substantial amount of data. However, there are exceptions to this, in the form of open source data recovery software. These data recovery programs are totally free and have their source code available publicly. In the sections below, we’ll give you a brief overview of the best open source file recovery programs currently available.

What Is Open Source Software?

To understand what open source software is, users first need to know what the term source code means. The source code of a program is what the end user typically never sees. The program can be modified or enhanced by making changes to the source code.

Simply put, open source software has its source code freely available to the public. Anyone can make changes or add to the source code. This means that no person or organization maintains exclusive control over it. A closed source or proprietary software’s source code is only available to the company, person, or organization that created it.

It’s important to know that not all open source software is free. These programs have different licenses that determine the availability of the code and how it can be shared. Additionally, users do need to accept the license terms before using an open source program, just like they would when using proprietary software.

Open source software offers numerous benefits to users, such as:

  • 💸 Less Cost: A glaring advantage of open source software is that it is typically completely free or only costs a fraction of what proprietary software costs.
  • 👥 Vibrant Community: Most open source programs have a closely interconnected community that critique the program and suggest new features or security fixes that can be added to the program.
  • 🔐 Security: Since the source code is publicly available, more white hat hackers can detect and fix any security flaws that they may discover in the code.

Best Open Source Data Recovery Software

Now that we know what the term open source software means, let’s take a look at some open source programs that specifically deal with data recovery.

There is an abundance of such open source data recovery programs on the internet. However, you can rest assured that the list below will take a look at the best out of the lot. Each open source data recovery software has been selected based on its functionality, features, ease of use, and more.

1. PhotoRec

As the name suggests, PhotoRec is an open source data recovery software that specializes in recovering deleted photos from your storage device. However, it can recover other file types as well. It has a text based user interface that may take some time getting used to, but it does the job well once you’re acquainted with it.

2. TestDisk

TestDisk is a companion to PhotoRec and is considered one of the best open source data recovery programs available.

3. Recuva

While Recuva is not open-source, it deserves a mention in this list because many users use the terms “open source” and “free,” interchangeably. Recuva offers amazing data recovery capabilities along with an easy-to-operate GUI, while being completely free for personal use. Recuva’s free version doesn’t come with any other bells and whistles. It solely focuses on data recovery.

What to Do if Open-Source Software Isn’t Enough

While free, open source data recovery programs can get the job done in many cases, paid programs offer more features, better data recovery chances and better tech support. If you’re unable to get back your data using open source programs, it may be worth your while to invest in paid data recovery solutions.

If you go with proprietary data recovery software, we recommend Disk Drill. Not only does it offer market leading data recovery rates, Disk Drill also comes with a plethora of additional features such as drive backup, ability to view the drive’s S.M.A.R.T.status, and the option to scan disk images.

The data recovery process is also quite simple:

  1. Download Disk Drill and install the program.
  2. Open Disk Drill, select the drive, and click on Search for lost data. Disk Drill will begin the data recovery scan.Disk Drill drive selection screen.
  3. Click Review found items to view recoverable files. You can view these files in real time as Disk Drill discovers them. You can opt to directly click on the file type you want to recover.Review found items screen in Disk Drill.
  4. Select the files you want to recover and click Recover. Double-click a file to see a preview.List of recoverable files in Disk Drill.
  5. Choose a recovery destination for the files. Click OK. Remember to choose a different location than the affected storage drive.Prompt to select a recovery destination.

Using open source data recovery software is a pocket friendly and transparent way to recover your missing files. However, with the variety of options available in the market, it’s best to use a program that is trusted. Since data recovery chances fall with each scan, you should still use established, paid software to get back data that is exceptionally important.
