Wow... that was easy. Thank you.


For the batch file:

for /r %%1 in (*.epub) do "C:\Users\Util\Desktop\New folder\CalibrePortableNEW\Calibre\ebook-convert.exe" "%%~dpn1.epub" "%%~dpn1.mobi"

All you need is to specify the extension of the file to be converted, the path to ebook-convert.exe (in my case, C:\CalibrePortable\Calibre\ebook-convert.exe), the extension of the file to be converted (again), and the output extension, mobi in this case.
