Thumbnail Regeneration

It did exactly what I needed... "Sort Photos into separate folders" HOWEVER.... I wish I knew that I should not delete my original photos from the i-phone camera roll. After that I was experimenting (not a good thing) and I pushed the "THUMBNAIL REGENERATION" button in settings and 75% of folders/pictures were erased.... And forever gone.
RECOMMENDATION: add warning/definition to what the THUMBNAIL REGENERATION button does.
So, I am biased with only a 2-Star because my pics are eternally deleted BUT the app effectively sorts into folders... otherwise this app would have revived a 4.5.
