If i now have over 2000+ videos downloaded in hitomi downloader and i wanted to search some selected video to see if whether the video is already downloaded and saved in device, i am unable to do it as of now.... if you do not understand what i mean by searching videos, please see the above image, it is more like filtering... i want to be able to search videos, you can also have a better understanding of what i am asking if you use the "search" feature in explorer.exe
