Recover4all does not allow deleted files to be saved to the original drive, as deleted files could be overwritten. Technically, it is possible to restore deleted files directly at their original location by writing on the drive containing the deleted files, but this changes the state of the disk. This is not a problem for successfully recovered files, but recovered files can turn out to be corrupted. To have the best chances in further recovery attempts, e.g. by a professional data recovery service, it is desirable that the disk with the deleted files was left untouched. For this reason Recover4all (like professional data recovery services) does not write to the original disk.
