I used ShinyMK's batch file (here) and modified it a to be a bit more flexible.
In this version you are able to set the name of the export folder (and I fixed the PAUSE in the end).
Simply use his Getting Keys and Preparation steps, except you use my Batch in Step 2.

When Decrypting it is nearly the same process as well. The only difference is that you have to enter the output folder's name in the beginning.

Thanks for sharing but don`t you think it is better to submit this improvement to his batch file?

Doesnt matter to me, this isnt an improvement at all, its pointless extra work having to name the folder.
