Normally "DCIM" is a folder in which all photos that were taken with camera are stored. When I tried to take a photo with Google Camera, the app instructed me to insert a sd card before taking photos (Nexus 5 doesn't support sd cards). I know that Google Camera also works without sd card, because it had been working before something messed up my Nexus's rom. I was looking with X-plore and ZArchiver and in both of them the folder "DCIM" appears as a file with a size of 0 bytes. I cannot delete this file, open it with an editor (Jota+) or create a folder with the same name and it is the only folder/file that is affected.
I'm using a Nexus 5 with Android 4.4.4 without any modification (like Cyanogen or root)
Does someone know what could have happened to this folder and possibly how to restore the folder or delete the file without root or factory reset? (If there's a way to delete this file, it wouldn't be a problem , because there wasn't a single photo inside before this happened.)
