I have an Android Asus Memo Pad 8 with o/s 4.4.2. 16 gb of internal storage, and a micro SD with 32gb of storage. I used to be able to copy files to the microSD either through a file explorer type of app, or save as from office type apps. Recently, I have been unable to do so and keep getting an error that says my o/s does not allow copying by third party software to an external drive. I'm so confused. I don't use my tablet much for copying files, but I want to make sure that I have files available on the device rather than on the cloud, because cloud storage is not always available to me. Can anyone give me an idea of how to do the following? Copy file from PC to Google drive in the cloud See the file on Google Drive on the cloud using my tablet. Copy the file from Google Drive to the external SD Card in my tablet. I am soooo confused.
