The Autoprune function compares current duplicate file search report entries against the file system to determine if they're still present. If not, the associated report entry is removed (pruned).
By default, Autoprune is triggered automatically after the Import function is used.
Autoprune is also launched automatically after duplicate files are processed with Duplicate File Detective (using the built-in moving, zipping & deleting features).
Note: In order to maintain good performance, the Autoprune feature does not investigate file system linkages (hard links, etc.) during its analysis.
