Kaleidoscope has been processing my files for a very long time.
Depending on your computer's processing power and the size of your data set, Kaleidoscope may take hours or even days to fully process your batch. The progress bar and "time remaining" figure are not always accurate, so the best way to see if Kaleidoscope is frozen or still processing files is to use Task Manager (PC), Activity Monitor (Mac), or another system monitoring tool. If Kaleidoscope is marked as unresponsive, then the program may need to be restarted. However, if Kaleidoscope's CPU usage is updating regularly, it is probably still processing files.
Please note that your input files and your output directory should be on an internal hard drive or solid-state drive. Using an external drive, SD card, or network drive can result in poor performance or crashing.
