I recently noticed a folder in my Gallery entitled "sdcard". In that folder were 19 copies of one single pic that I downloaded from my Western Digital 2TB NAS drive using the WD2Go app. I deleted the pics and all that is left are the file placeholders. This presents a problem seeing as I con't figure out how to remove them completely. I searched through Astro but can't find the folder or anything related to null files.My phone is rooted and running ICS.
