18 Best Free Data Recovery Software and Shareware to Get Files Back for Free
You do also delete or lose very important Word, Excel or PPT documents, games, videos and files unexpectedly? Here are 13 best data recovery freeware and shareware tested, suggested and posted by iCare Recovery for you:
1). Recuva
As a free data recovery app, Recuva is often downloaded and used by many people to retrieve Pictures, Documents, Videos, Compressed, email and all other files from memory cards, computer Recycle Bin folders, partitions, hard disks and other storage devices without any cost. It is easy and fast for everyone to use.
However, the data recovery results may not be so satisfying, especially when the scanned storage device is seriously damaged.
2). iCare Data Recovery Free
iCare Data Recovery Free also allows people to retrieve lost data back without any limitation. With a user-friendly interface and two effective data recovery modes, this freeware always helps take deleted or lost data back with high efficiency after accidental delete, format, drive RAW file system errors, not formatted errors, corrupted drive or memory card problems, virus infected drive issues, sudden computer power loss or hard drive corruption problems, etc.
However, it doesn’t works as well as its iCare Data Recovery Pro version, a paid version. Moreover, it also does not offer a Mac version yet.
3). PhotoRec and TestDisk
As completely free data recovery utilities, PhotoRec and TestDisk are produced and designed with similar interfaces and data recovery features. And, except the common data recovery functions, the TestDisk often works better in dealing with partition data recovery issues.
However, no matter which one you will finally choose to use, the DOS-like interface could be a tricky nut to crack.
4). PC Inspector File Recovery
With common language services and wonderful three file recovery modes, PC Inspector File Recovery is also a nice chance for people to retrieve data from storage devices with FAT12/16/32 and NTFS file systems.
However, during testing, this software fails to be closed often and also does not support CD-R, CD-RW, DVD and the like storage devices.
5). Free Undelete
Free Undelete is also data recovery freeware to help undelete files and folders from Recycle Bin, USB hard drives, flash drives and memory cards easily and quickly. However, it is only free for personal user and does not work on Windows 98, Windows SE and Windows ME PC.
6). Wise Data Recovery
Like other data recovery tools, Wise Data Recovery also runs fast and is able to retrieve different photos, documents and files from commonly-used storage devices for free. With diversified language choices, fast Search tool and portable versions, this freeware is also a good tool to try. But, also remember that it does not work on a Mac or Linux operating system computer.
7).Glary Undelete
Glary Undelete is also another best data recovery freeware that offers file filter function for people to easily preview and search deleted or lost data back. Its file analyzing function (which will analyze file recovery possibility) is realty worth trying.
8).Pandora Recovery
With a sweet Wizard guide, Pandora Recovery is really easy-to-use data recovery freeware which suggests user to check Recycle Bin at first and offers three recovery methods to find and recover lost data back quickly and effectively.
9).Puran File Recovery
As a last completely free data recovery app, Puran File Recovery also offers wonderful data recovery features, like freely selecting desired language before installation, simple instruction windows to introduce major features and functions, and four scan options to retrieve lost contents with ease.
However, its deep scan takes a really long time and also allows people to preview images within 10MB only.
10). Other Best Free Data Recovery Shareware
Of course, there are also many other best data recovery shareware introduced in that iCare Recovery article. However, they can only help recover a limited amount of data for free.
