Last night, I copied five mp3 files from my laptop to OneDrive, with the intent to download them to my cell phone. After I was done, I opened the folder on my phone, but I could only see three of the files. I checked the folder from my desktop PC, and it also showed only the same three. But when I rebooted my laptop and looked again, it showed me all five of the files right where I dropped them. What’s going on here?
The laptop is on Windows 8.1, the phone is Android 4.0.4, and the desktop is a dinosaur running Win XP 2002 SP3.
