Here is what I do in Windows 10. It's a pain but works. I copied this below from where I helped someone on another forum:
What I do to get past this is change the name of the directory on the card using Windows Explorer. Change the name with the computer before you ever download it to the computer.
For instance, Each camera will put the pictures under a directory called "Reconyx 100." Before downloading them to the computer, I give them a different name while still on the card. I usually just do 1 for the first card, 2 for the second card, 3 for the third card, etc, etc, etc. Make another directory on the computer that these go to with the date of the pull and put each of these in that directory.
Now the pictures are going into different directories on the computer and even though many of the pictures themselves will have the same file name, there is no conflict, because they are in different directories.
Another helpful tip is to use the "cut" instead of "copy" when you move them to the computer. That way the card is already erased when the pictures are moved, so it saves a step in not having to erase the card. Also just hover over it when changing the name and cutting instead of clicking on it. This saves some time too.
Also, if you are going to use the viewer that comes with Windows 10, you have to start the computer where it has an Internet connection and then let it sleep while driving to the field. If you boot up the computer while away from an Internet connection, the viewer will not work until you get home.
Can't wait for the next wonderful software enhancement so they can mess it up even more.
