I use Dropbox to store all my music files(MS word). I use my Windows 10 PC to create all of the files. All of the files upload fine into Dropbox. I make the folder contents available off line on 2 Android tablets. In previous Dropbox versions I could see if all the files were updated with the file unticked till synced then the green tick when synced. I am never sure now if the full sync is complete (I have around 800 song files). The "green tick" seems to be there BUT I have found that some files, not many, are not available when I get to an event , one tablet may have the file but not the other (I turn wifi off when I leave home as I don't want random pop ups etc). Am I missing something or can anybody point me to a solution. A quick way of confirming sync would be fine. Thanks. Dave
