Yeah, I have one, a 32Ger I think it was, in my MAC too with over 400 slides I took, mostly overseas while in the Navy, that I used this contraption I bought on Amazon to put the slides on that card.

Anyway the SD Card I am referring to is one I placed in the Smartphone to add to the internal memory, but has its' limitations, not being able to move or copy everything I thought I could (APPs, system files, and such)to free up the 32G memory somewhat. SURPRISE, LOL, the Manufacturer of the phone probably says, "You want a larger memory phone, BUY ANOTHER bigger one :-).

Blues/Star, if you have an android smartphone, go to your SETTINGS>>>Storage. You may see that Safe Folder there, or you need to click on, "Show," Safe Folder, I believe it said.
