If I use the file manager app that is installed on my Nexus 7 I can see all the files on my device. Pictures, documents, music files, etc. If I go back to my Win10 machine and look at these same folders, I get the message, "This Folder is Empty."
As if that isn’t weird enough, if I copy a file from my Win10 machine to, say, my Pictures folder, I can then see that filename is on my Nexus 7 using either my Win10 File Manager or the File Manager installed on my Nexus 7.
I did some Googling and the most common response to USB file transfer problems is to make sure you have the proper MTP driver installed on your PC so it can read the Nexus 7 file structure. I’ve double checked that and I do have the correct MTP driver. Anyway, the fact that I can transfer files from my PC to my Nexus 7 and see them pretty much confirms I’m using the correct driver.
In summary, when my Nexus 7 is connected to my PC I can’t see any files using my PC’s File Manager, but I can see them using my device’s file manager app. I can freely transfer files to/from the Nexus 7/PC and I can see these newly transferred files using my PC File Manager. But I can’t see any files on my device using my PC to look for them.
What in the world is going on? How do I fix it so I can download files from my device to my PC?
