I had a few very large video files that were taking up a lot of space on my phones HD, so I decided to shrink them to 80%, which took the file size down by half. Great. But when I checked the space on my HD, it had actually gone up by the same amount that the newly rendered video was. I tried going into trash, optimizing and even restarting my phone, with the same result.
I guess I could have saved as a copy then deleted the original, but I figured the way I did it would have overwritten the original. Any ideas?
