Galaxy S3 mini SD problams

[AC Question]

I got a Samsung s3 mini and I was running out of space so I bought a Samsung 64 GB micro SD card and when I turned it on I got a message saying SD card safe to remove and when I went onto setting,storage I tapped on mount SD card a it and it said SD card safe to remove. So I went onto my flies and it only has sdcard0 not SDcardext I keep on looking for a way to solve it but it never works.

How can I access my SD card?
How can I transfer my photos onto my SD card?

Welcome to Android Central! Can your computer read the card if you insert it there? If so, using Windows Explorer, right-click the card and select Properties. What filesystem is it formatted in? FAT32, NTFS, exFAT? FAT32 is the most universally compatible--the others don't always work in Android devices.
