I decided to copy some movie files that are in a folder on my desktop PC to my VTAB's SD Card. I connected the USB cable and selected the card, and, using Windows Explorer, I copied the folder to my VTAB's SD Card. Afterwards, using both ASTRO and ES FILE Explorer, I my searched my VTAB for my new files and couldn't find them. I removed the SD Card, put it in an adapter, and inserted it in my PC whence I found that my folder and files had been copied into a folder named "EXTERNAL" that I had not created and which is ignored by search apps. Is there an explanation as to why the search apps don't search the external folder?
