It’s an emo day for me today, when transferring files from my phone memory to memory card I accidentally pull off memory card. I lost all my videos, music and porns. So the lesson, do not pull of the card when transferring, I thought it was already transferred cuz I leave it there for a minute already. So I insert it again, the folders were all empty but the memory storage is still full. So I did the “error checking” on the drive’s “properties”, after done, a hidden folder appear and all files were inside but under .CHK, you can rename it manually or you can find a software. Easy, my pictures files are all around 500kb per file or less while music and movies are around 5mb per file. The headache is I got total of 2400 files.
