I can't find my .nomedia folder or the folder it is in anymore, but the files still seem to be there

I recently followed the advice posted from https://android.stackexchange.com/questions/37565/how-do-i-keep-audiobook-separate-from-google-music/62542#62542 by @Tzunki in order to keep my audiobooks out of Google Play Music. I made a .Audiobooks folder and put them all in there and then added a .nomedia folder for good measure. It worked great, but now I'm trying to delete out an old audiobook and add a new one, and I can't find the folder or any of the audiobooks. I've tried searching for the files and the folder names, etc., but it looks like they are all hidden somehow and I can't find any of them in order to edit them. I went back to my audiobook player to make sure they are still there and played them and they play. I checked the root folder for the files in my audiobook player and it shows /storage/emulated/0/.audiobooks (which is not where I told it to look when I created the .Audiobooks folder) but I looked there and there is some data file instead of the audiobooks, so I'm thinking it is just like a bookmark so it knows where in the audiobook I left off? I've tried to just type in Computer\Galaxy S6\Phone\.Audiobooks, but it says Windows can't find it. Also, I thought I might try to re-create it, and see if it repopulated with my files but when I try to change the name of my New Folder to .Audiobooks, it won't change, it just reverts back to New Folder. Any help you can offer would be great.
