Why can't I open the files from the new micro sd card?

I had a 8GB Kingston MSDcard (HC) and I bought a 32GB MSDcard (HC) to gain some space on my device because I have been having troubles updating apps due to insufficient space storage available.
I copied the files from my old SD to the laptop and transferred them from the laptop to the new SD.
when I turn on my phone I cannot open files like .pdf or music.

Some help please!
