Hi I wonder if anyone could shed some light on the strange issue I have not experienced before? Ive used Photoshop for ages so Im not a beginner I use a MacBook Pro and PC. Recently I have been editing Jpg's on the Mac and am suddenly finding that if I copy them to and load them on the PC, most of the jpgs appear to have no .Jpg extension, and they appear as FILES, and cannot be opened in Photoshop on the PC. Has anyone had this happen and if so could you please tell me why this is suddenly happening. Its not happened till now. Many thanks
