I am looking for a gratis PC program which will let me connect to my Android phone. USB connection is fine, WiFi is a bonus.
It should be aware of all the common file locations and allow me to transfer music, ring tones, photos (hopefully ebooks), etc back & forth.
I would also like to be able to have full access to the file system. So, both easy & expert mode.
Backup & restore would be nice.
A prime concern is the lack of obtrusive advertising. I realize they have to make money somehow, so can live with an app store, which I can ignore.
I used to use MoboRobo, but it doesn't seem to work with my new 'phone (plus, when I go to their "download for Android" page, Google has a large, fierce, security warning)
