DeepakP Unforunately, every time you install Tonfotos on fresh system, rescan is necessary. Internal database is not meant to be portable. However, the data will not get lost. All your metadata edits are already embedded into files, and face associations are stored into ini files, family ties are stored into dossier files, please read more about it here: https://community.tonfotos.com/d/186-version-150-people-data-synchronization All this information will get automatically restored during scan.
The only thing that might get lost are albums, but if that is the nature of albums in Tonfotos. If you want more permanent albums, use Tags instead.
