Makes Duplicate Of File When Opening Pictures On A PC
What does it create that duplicate file with the ._ before it?
When I plug it back into the mac that ._ file is not there.
Mac OS stores "resource forks" (icons) in image files but PC users get two files when they are shared via HD, CD and even when using a PC to view the contents of any Mac directory on a PC.
My simple fix is to "delete" the resource fork prior to sharing with PC users so they don't get confused.
CMM's can do this with a right click prior to sharing and most image apps can also delete that resource fork file.
Mac Mail app allows the "Send Windows Friendly Attachments" which also removes the resource fork file so viewers are not confused.
