If you have accidentally cleaned up the Recycle Bin that still contains some important files for you, Recovery Toolbox File Undelete Free will scan your entire internal hard disk (HDD) or external hard drive that contains the file and then try to recover it. . The program only works with drives that use the NTFS file system. To cancel the file removal, the program will perform a full scan of the disk to analyze it to determine whether the deleted file can be restored. In some cases, however, file recovery can be impossible for a variety of reasons.
