It is highly recommended that you keep taking real-time backup, have a backup drive in your computer which automatically duplicates data but still it may happen that you loss some important data of yours. Below stated are five data recovery tools which are mostly free and available on the net. We have classified them into two groups, for Windows and for other operating systems.
FOR WINDOWS OPERATING SYSTEM ONLY
Undelete Plus is file recovery application that works on all versions of Windows and incarnations of the FAT and NTFS file systems. Undelete Plus assigns a recovery probability to files it finds based on how damaged the file is. One can sort files by type, set filters based on time and size to avoid sifting through every deleted file on your disk, and keep folder structures intact during recovery.
Restoration can be used for all versions of Windows file systems. It lacks some of the advanced functionality of other applications but does have basic file-name search and the ability to sort by file parameters such as size and filename. It performs well for restoring files from disks. Restoration weighs only 406k and would make a great addition to any Windows-based USB toolkit.
Recuva is another Windows-based tool which can resurrect missing files using either the file-recovery wizard or the application’s manual mode. The file-recovery wizard is handy when you’re sure your data is gone but you’re not quite sure where it is! Recuva lets you narrow your search type to various file types and you can set the search location to everywhere on your computer. If you don’t need the wizard you can jump right into manual mode and get to work searching where you know the file should be.
