From personal memories captured in photos to crucial work files, the loss of data can be distressing. Whether it’s due to accidental deletion, formatting errors, system crashes, or malware attacks, losing important files is a common problem. While there are many paid options to retrieve lost data, not everyone can or wants to pay. This has led to a growing interest in unlimited data recovery software that is free to use.
When you delete a file from your computer, it isn’t immediately wiped from the storage device. Instead, the space it occupied is marked as “available,” and the file becomes invisible to the operating system. Until new data overwrites it, recovery tools can retrieve it.
There are three main types of data loss:
Accidental deletion
Formatting or partition errors
Drive corruption or physical failure
Software-based recovery can handle the first two and sometimes the third, depending on severity.
The Myth of “Unlimited” Free Recovery
Many programs advertise themselves as “free,” but only a few offer truly unlimited data recovery without imposing restrictions. Common limitations in most free versions include:
Data cap (e.g., recover only up to 500MB or 2GB)
Disabled features unless you upgrade
Limited file type support
No support for RAW or deep scans
No technical support
The term “unlimited” should therefore be scrutinized. In this guide, we focus on tools that:
Do not have a recovery size limit
Are genuinely free for personal use
Offer full functionality without a paid version
Top Truly Free Unlimited Data Recovery Software
Let’s look at free data recovery software that offers unlimited recovery capabilities.

Lesser-Known But Functional Unlimited Recovery Tools
These tools may not be as widely known but can provide powerful recovery capabilities:
6. Kickass Undelete
An open-source Windows tool that recovers deleted files from FAT and NTFS drives.
7. Glary Undelete
From GlarySoft, this tool offers unlimited recovery with a clean UI and file type filtering.
8. FreeRecover
Another open-source utility designed to recover lost files from NTFS drives.
Each of these is limited in some way (file system support, outdated UI, etc.) but they are still free and offer no size caps.
What You Should Look for in Unlimited Data Recovery Software
When evaluating recovery software, keep the following in mind:
1. Recovery Depth
Can the software recover data from:
Deleted files
Formatted drives
Corrupted partitions
RAW drives?
The more versatile the tool, the better.
2. File System Compatibility
Ensure it supports the file system used in your device:
NTFS (Windows)
FAT32/exFAT (USB drives, SD cards)
HFS+/APFS (macOS)
EXT3/4 (Linux)
3. File Type Support
Check if it supports recovering photos, videos, documents, compressed files, and application data.
4. User Interface
Some powerful tools lack a graphical interface (like TestDisk and Windows File Recovery). If you’re not tech-savvy, choose tools with an intuitive GUI.
5. Preview Feature
The ability to preview files before recovery ensures you restore only what’s necessary.
6. Portability
Portable versions don’t require installation and can be run from a USB drive—handy when recovering system drives.
Tips to Maximize Success with Free Recovery Tools
Recovering lost data isn’t always guaranteed. Here’s how to increase your chances:
1. Stop Using the Affected Drive Immediately
The moment you realize data is missing, stop using the device. Continued use risks overwriting recoverable data.
2. Install Recovery Tools on a Different Drive
Never install the recovery software on the same drive you’re recovering from. This could overwrite deleted files.
3. Use Deep Scan Mode
Most tools offer a deep or thorough scan mode that takes longer but finds more files.
4. Scan All Partitions
Even if you know where your file was, scan all available partitions. Deleted files can sometimes be relocated across sectors.
5. Recover to a Different Storage Location
Save recovered files to a different drive or USB stick to avoid further corruption or overwriting.
When Free Software Isn’t Enough
While free recovery software can handle most logical data loss scenarios, there are situations where they may fail:
Severely corrupted drives
Encrypted storage
SSD with TRIM-enabled deletions
Physically damaged devices
In these cases, consider:
Commercial recovery tools like R-Studio, Disk Drill, or EaseUS (after evaluating their free features)
Professional data recovery services, especially for failed hardware
These services are often expensive, but when your data is irreplaceable, it may be your only option.
Are Free Recovery Tools Safe?
Generally, yes—especially open-source tools like PhotoRec and TestDisk. However, be cautious:
Avoid unknown freeware sites — they may bundle malware
Read user reviews before downloading
Scan installers with antivirus tools
Use trusted platforms like GitHub, SourceForge, or the official developer websites
Realistic Expectations with Free Recovery
Free data recovery tools, while powerful, are not magic bullets. Set realistic expectations:
Some files may be partially corrupted
File names may be lost in deep scans
Not all data is recoverable, especially on SSDs where TRIM has erased deleted blocks
Despite this, thousands of users have recovered critical data using nothing more than free tools. Patience and proper technique matter as much as the software used.
The idea of unlimited free data recovery software seems too good to be true—but it’s not. Open-source and community-backed tools like PhotoRec and TestDisk have been successfully used by professionals and casual users for years. These tools offer full, unrestricted access to your lost data, with no surprise paywalls or recovery limits.
