TimTheJedi Sorry to hear about the issue. Most of the time prediction works great, but for some reason it failed in your case. Hard to say why, it could be you addded more files to the folder after it already counted number of files, who knows. Right when it starts, Tonfotos counts number of files in your folder and uses this info to asses the completion rate, and as result, estimated time. However in your case it looks its calculations do not match the reality. However, Tonfotos will not update this counters until it finishes, so I guess the only option now is just to wait.
