Recover4all - Version 1.04 The Recover4all data recovery software undeletes accidently deleted files. It does not matter if the files were in the recycle bin (and have been lost since the bin was emptied) or were directly deleted. The deleted files can be restored with a few mouseclicks. To prevent already deleted files from becoming overwritten, Recover4all does not require installation and can run from a floppy disk.
