I found a folder called ".eCtcQjbu1dgnvtFnvnr6yepTp1M=" in sdcard0 while I was cleaning up my phone's Internal Storage. In the folder, there's an unnamed file labeled "NOMEDIA" under Windows explorer. I can't seem to delete the folder; it keeps reappearing with the file. I don't remember seeing these files before..what is it?
