Hello, I don't know how to delete truly files from my flash drive. Whenever I press cmd+backspace or simply drag file to trash, it doesn't delete fully, i.e., space available doesn't increase on flash drive, the icon just disappears. When I plug it in using Windows, I can see .Trash and .Spotlight<something> folders which are hidden. In .Trash I see my deleted files, but how the heck can I really delete them off my flash drive ? This is driving me nuts.. I often just copy all my content to hard drive, format flash drive and then copy back my content.. PLEASE help me! Thanks in advance!
