The way I do it for my collection is by using these 5 essential softwares
1)Ultra Search
One of the fastest file searching software with wildcard capabilities, I put all my finished downloaded files at a directory and then use UltraSearch to delete all misc "advertisement" files that usually come with the download by searching just for the extension (example .mht or .url). I usually add 50+ downloads in my queue and can't be bothered to select just the movie files and photos
2) Bulk Rename Utility
After clearing all the junk files my next step is to name them properly and removing certain texts like [thz.la] or p2p.wowweeelubba.SNIS-404 for 200 folders isn't fun. This is one of the best tool for the job.
One of the most used function by me is to Rename files from foldername automatically, so I only need to rename each movie's folder properly. Also I use a batch file to move all movies that came without a folder into it's own folder according to the files name
3)JavMovieScraper by DoctorD1501
One of THE best data scraper I've used to date, though the creator has gone MIA for at least a year but someone by the name of Wizell has taken over the project.
This java program is able to scrape 99% of JAV movies from sources such as DMM, Javlibrary, Javbus, and also uncensored ones from AVentertainment, Caribbean, Heyzo, 1pondo.
What it does is download Covers and creates a .nfo file with multiple Actress names, english titles, subgenre, year of release so that you can easily search for whichever actress you want a list of, then again the accuracy of this data is strongly depended on the sites it scrapes for, personally I prefer scraping from Javlibrary as the actresses list are mostly accurate and I can always submit a change to that site if I find the data to be inaccurate.
Also to use this tool you must make sure the files are named *CORRECTLY* or you'll get wrong titles scraped
4)DupeGuru
I use this to find any duplicate movies I may have downloaded
5)KODI
Finally what's the point of all that data scraping if you don't have a way to properly 'view' them? Previously known as XBMC, KODI feeds on all the data you've scraped and you can browse all your collection by Year, Actresses, Genre and view all the movies via covers. Very customizable experience
