Hello I have an HTC Sensation and I have a problem with my SD Card. I was trying to film with my phone and all of a sudden the memory was full. There is no music on, and only a few pictures. It says i have about 1 GB free, It's an 8GB SD Card. And when i plug the phone to the computer and add the size of all the folders together i get almost 2 GB. So i should have around 6 left. How come i only have 1 GB left? Where are these secret files that takes up so much space on my SD Card? How can i solve this? Can i format the SD card and my phone will be fine or are there any files on the SD card that the phone needs? I dont have that many apps on there cause i did a factory reset a week ago. Its really bugging me and i hope someone can help me! EDIT! Problem solved! I found how to view hidden folders and apparently everything i threw in the trash on my friends Mac ended up on my phone when i used it as a disk drive.. what the heck, go to hell apple haha Apparently my friends Macbook thought my HTC was a trashcan, not cool Apple, Not Cool.
