Data Recovery Tools - A good free data recovery Tool

It's always hard to find a good freeware that suit our need, it's even more difficult when we search a data recovery tool, One day I came accross Undelete Plus , this free data recovery enables you to undelete files that have been emptied from the recycle bin. Undelete Plus quickly scans a specified drive and show you a list of files that can be recovered, along with the status for each file (very good, good, bad etc.) indicating the likeliness of complete recovery. Undelete Plus automatically sorts the files based on file type and folder, making it easy to find specific files, and you can also apply a filter to search for a specific file.
