I noticed that the file system has some old folders from old applications that I had installed.
How do I get rid of this? Which maps do I not remove, etc?
Or how do I do a completely clean installation of the operating system?

TWRP doesn't wipe any of your personal files unless you wipe your "personal data" not just factory reset or system. I've done it many times and never lost any internal data or downloaded SD card files. The other issue with formatting your SD card as internal storage with CM13 is I've read that you can no longer do TWRP backups due to the encrypted storage issue but I haven't heard of anyone actually confirming that so you might try a recovery backup and let us know whether it's true or not. Also I believe you would have to reformat your card as external storage and lose what is already on it to unencrypt the card. The internal storage option is good for phones with low internal nand storage or those who want their whole phone, SD card and all, encrypted. Good luck.
Hi, best that you do titanium backup of all apps you currently have and backup whatever messages, whatsapp, music, photos, etc. Boot into recovery and use the factory reset and wipe /system to fully wipe the internals, flash cm13 nightly and gapps, clear dalvik and voila, boot up and set up device like brand new.
But in that case, where do I store the gapps and cyanogenmod installation file, if I wipe everything?
SD card? if not I do believe twrp doesn't delete the files in the root folder of your device so use that.

search google on how to copy files to your phone while in recovery.

Alright, I managed to install cyanogenmod cleanly now! Thank you!
But now it keeps wanting me to format my external SD card so that it's included in the phone's storage or whatever, and now when I did, I'm left with the phones default storage capacity?
Oh i assumed you knew about this, you shouldnt format as internal storage, it will encrypt your sd card so you vant just plug in the sd card to your computer directly and copy stuff over :( on the other hand if you are gonna leave the sd card in all the time should be fine, but the storage capacity you gotta search around for some fixes.
I didn't have any important files on it so it doesn't really matter. I don't unplug it like ever so it's alright. I just wish I would be able to see the full storage when I plug the phone into my computer etc. I got really annoyed by the notification in the notification bar which made me format it just to get rid of it. Is there no way to restore it either?
To fix my SD card, I had to plug it into an computer and format it.
