Hello,

I have two photo files that are locked, I can't open the folder. How can I open it?
When I try to open it, Windows tells me that a software extension is needed. In this case, what is the appropriate software to open my folders? All my travel photos are in there, and I don't want to lose them. Can you please help me?
Thank you in advance.
