I can't find my .nomedia folder or the folder it is in anymore, but the files still seem to be there So i recently followed the advice posted here: How do I keep audiobook separate from Google Music? 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 rood 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?
anyways, any help you can offer would be great, thanks.  

*edit with a little more info:
I've tried to just type in Computer\Galaxy S6\Phone.Audiobooks, but it says  Windows cant 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. Just reverts back to New Folder.
Many thanks to @gertmenkel! I found the hidden files using ES Explorer and deleted out the "." so that the file wasn't hidden anymore.  the audiobooks are still not in my google play music because of the .nomedia file i have in there.  so the "." in the audiobooks file name was overkill.
Btw, I'm too new here and I'm not sure if you get points for posting a good solution @gertmenkel, but if you do i dont want to take yours away so if you post the solution i'll delete my own.  Thanks again!
