ReviveR is an advanced file undelete and data recovery tool. The ReviveR data recovery program is easy-to-use and does not require any advanced technical skills. We have made working with ReviveR as comfortable and straightforward as possible.
Tech Assists' ReviveR can recover deleted files even if the files were deleted from the recycle bin, or if applications (which normally bypass the recycle bin) deleted the files. ReviveR can also recover lost files even after a complete format. ReviveR is a safe, impactful and read-only data recovery solution.
Product Features
Works under Microsoft Windows XP / 2003
Supported file system: NTFS 3.1 (as formatted by XP and up)
Unique Validation Engine, allows predicting the recoverability of files
Protects data from being overwritten while working with the software
Includes a free FAT module for legacy FAT12, FAT16 and FAT32 file system support! This version is free for registered ReviveR NTFS users and is not sold separately.
Deleted File Recovery (Undelete) Mode
Lost File Recovery (Unformat) Mode for recovering files even after a complete format
Recovers from any NTFS formatted storage media.
ReviveR can be used to recover files from:
Accidental file deletion, even after the Windows Recycle Bin has been emptied
Delete actions that bypassed the Recycle Bin (files deleted by applications or from a command prompt)
Volumes that were (accidentally) formatted
Various other types of volume corruption
Recovery Modes
Undelete Mode:
Select this mode if you are trying to recover files that were deleted (i.e. files that are no longer in the recycle bin, or have been deleted by applications, deleted while holding SHIFT-key, or other accidental actions). The partition that contains the deleted files must be accessible and un-damaged.
If 'Deleted file recovery' was selected ReviveR will only show NTFS formatted drives.
Unformat Mode:
Select this mode when partitions have been reformatted. In this mode ReviveR will discard the 'active' file system and scan the drive for file system structures. This scan will take time. Based on scan results ReviveR will try to reconstruct a file system in memory from which files can then be recovered.
In the next step ReviveR will display all logical drives (including NTFS, but also FAT/32) and physical drives. This is done so that you can select a newly formatted FAT partition that was previously formatted as NTFS. So, even when a non-NTFS drive is selected from the list, ReviveR will still treat it as an NTFS formatted drive!
Validation Engine
ReviveR (NTFS version only!) features a file validation engine. Many file formats have recognizable structures, headers and 'magic bytes'. For file types that are recognized by the validation engine the internal file structure is partially examined. If the extension of a file matches found structures, headers and magic bytes the file is probably intact. If the file extension does not correspond with found structures, it's almost certain that the file is corrupt.
The following file types are validated:
".JPG", ".GIF", ".ZIP", ".CAB", ".EXE", ".DLL", ".OCX", ".WRI", ".BMP", ".DOC", ".PPT", ".XLS", ".PDF", ".RAR", ".MP3", ".MPG", ".MPEG", ".MPE".
How accurate is validation? Well, no algorithm can replace the human eye! An algorithm can search for common structures and compare these to known-to-be-good values. It can however not determine if the file it is examining is a picture of a windmill or a picture of a boat. Manually verifying files after recovery is the only way to verify if files are intact or corrupt.
Recovering Files In Demo Mode
ReviveR allows you to recover files in demo mode so you can fully review the program before buying.
However when recovering files using the demo version:
You can only select and copy one file at a time
You can not copy folders
A 3 second delay occurs before the selected file is copied
A pop-up message is displayed with each file copied
These limitations are removed as soon as you register ReviveR! To prevent you from having to scan a disk again, ReviveR immediately switches to licensed mode once the license key has been entered so you can then start recovering your files. The license key can be entered by clicking the appropriate button in the toolbar.
