I wish to increase the memory capacity of my Samsung Galaxy S5 phone by swapping the present 16GB SD card for a 128GB one. Is it simply a mattery of copying all the folders and data from the existing SD card onto the new one before installing it in the phone -- e.g. by connecting my phone to my Windows 10 PC by USB, putting the new SD card into my PC's slot, and then using Windows File Explorer to drag and drop the folders and files? Or should I install the blank new card in the phone first, put the old card in the PC's slot, then use Windows File Explorer to drag and drop all the files and folders from the old card onto the new one in the phone? Will either of those methods result in lost data, or the phone not working correctly? I've already got all the apps that I can onto the SD card because the phone's memory is almost full. Is there a better, or 'correct' procedure for doing the job?
