Use Last Chance recovery by file signatures

This recovery method is helpful when primary recovery methods (QuickScan and SuperScan) either haven't detected your files and folders, or hundreds of volumes are being detected and you cannot locate or recover your files from them.

This recovery method tries to detect all un-fragmented files based on their standard signatures. In most cases we will be able to detect and properly recover the contents of lost files.

However we won't be able to detect the file system attributes (eg. original filename, creation date, modification date etc).

Detected and recovered files will be grouped by file extension only, and will have abstract file names. The File Organizing feature will help you to group your files into folders based on extended file attributes (available for some file types).

To use Last Chance recovery method:

1. Launch Active@ UNERASER and click LastChance toolbar button, or click LastChance from Action menu
2. Select the drives you wish to analyze, or de-select disks you are not interested in, and click Next
3. Confirm file signatures to be analyzed and de-select file types you are not interested in recovering (this will speed up the process significantly)
   
   
4. Click Start button and wait until the scan process completes
5. Review found by signatures files, Preview file content to make sure files are recoverable and it's what you need
6. If needed, re-organize found files in folders by specific attributes using File Organizer
7. Select file groups or particular files to be recovered and click Recover toolbar button to recover them all at once
