Exhentai downloader stopped working and I couldn't find a working version, the mangareader script was working though, so I niggerrigged a script.
setlocal EnableDelayedExpansion
@echo off
for /D %%f in (*) do (SET _foldername=%%~ff ) && (SET _foldername=!_foldername:~0,-7!) && (mkdir "!_foldername!" || (echo folder already exists)) && (xcopy "%%~ff\*.*" "!_foldername!\")
Here's how it works if anyone is having a similar problem.
Pretty much what it does is go through all folders in the current folder and copy the files to a new folder without the last 7 chars.
The way it should work is you use mangareader to get the page full of images, then save the page to a folder, it'll create an html file and a folder with all images and fonts. After you have all the pages you want there, you put the script in the folder and execute it, it'll go through all folders (e,g /loliporn_files/ ), create a new folder without the _files (e.g /loliporn/) and copy all the files to that new folder. After that you can delete all html files (it should delete their folders automatically) and stay with the new nice folders.
