I'm hoping I'm just having a blonde DAY, but I can't figure out how to access the files on my SDHC. I had an 8gb card in my tablet, and when I got the message my tablet was full, I assumed I'd filled up the card as well. But I finally got an adapter so I could put it in my computer & look at it, but the only thing on it was a couple of empty folders. So I copied a video onto it & put it back in my tablet. But I can't find the video using ES File Explorer. Can someone tell me how to access the files on the card? Also, I took out the first card & put another in. I got the message that it was damaged & might need to be reformatted. I put it in my computer, reformated it, put a picture on it, & put it back in my tablet, which still told me it was damaged and might need to be reformatted. Any suggestions about this?
