TECHNICAL BACKGROUND
This document explains some terms used in the help system.
1. Supported operating systems and file systems
Recover4all Professional can recover deleted files from local drives with FAT and NTFS file systems.
All files that can possibly be recovered by the full version are already displayed in the unregistered version.
The program runs under Windows 10 (technical preview), Windows 8/7/Vista/XP/2000 and 2012, 2008, 2003 Server.
2. Recoverable and unrecoverable files
How is it possible that a deleted file is still on the disk?
In many cases only the pointers to the file data are deleted and the file data remains unchanged. But sooner or later another file will be saved to that location. Then the deleted file is overwritten and unrecoverable. If no data is saved to the drive, the deleted files will remain on the disk forever (but see the warnings in the overview and this topic in the FAQ). It is in general advised to use Recover4all soon after deletion.
