During the past three days, my computer got stuck again in editing Bon Dance videos and stopped responding frequently. So I needed to delete or move in order to get enough space to do video-editing.
To my surprise, there were 127,200 Files (4821 folders) in my picture folder and 877 files in my video folder. No wonder it took time for such a simple job. In order to look all files with pace of one photo per a second, I'd need at least 127,200 seconds which is 35.33 hours!!! So I gave up deleting unnecessary files. Instead, I bought another 4TB hard drive at Costco. Yes I chose to save time and to use money for the time.
Now I can work with my computer and do blogging again!!!
