Do I need java to see my sd card on pc?
I can not see my sd card on my pc. Do I need java?
Only if it's JavaOS or Java Desktop System. Other Java based operating systems aren't intended for PCs. The cardreader must be new enough to read that capacity card, and have a driver (which won't be written in Java). As you have not mentioned what OS or PC or SD card, that's as much as anyone can say.
