I had several important which I had downloaded on my MAC and stored it in a pendrive. Now I am using a windows laptop. When i connected my USB device to open the files, I am not able to do so. The file names have a ._ in front of their filename and the icons look semi transparent instead of bold. How can I open these files now
Those are what are generally referred to as invisible files. You can either remove the ._ by renaming them. You can do this with a couple of different software but I recommend Advanced Renamer since its free and open-source. This is apparently a bug of some network shares
