After exchanging my SP3 the other day I got everything shipshape on it afterward. Couple of days later I looked in some work files that were on OneDrive (on my computer too). A day later I looked at one or two of those files and...the file folders were there, but the content had vanished! I have an Asus T100 so I opened File Explorer on it and went to OneDrive and...there was the file content missing on OneDrive on my SP3! Fast forward to Microsoft OneDrive support. Told them my problem. They asked to remote in to my SP3. I agreed. They did arcane things I couldn't even follow as I watched the mouse cursor zoom in all directions, windows open and close like little explosions, then they asked to remote in to my T100. I agreed. Same voodoo watching my T100 - reminded me of looking in a kaleidoscope as a kid. Ultimately they reset OneDrive in some fashion on the SP3 and T100. The SP3 ground through the OneDrive deal within a short period of time, but still no content in those particular files. I noticed OneDrive on the T100 was still going at it so I left it alone overnight (takes a long time to upload/download stuff between OneDrive and a computer). This morning, I checked my OneDrive folders on my SP3 that had missing content yesterday...boom...today, all content is where it should be. Some of you probably understand OneDrive completely...me...I don't. I understand the basics, but there's no way I could have unraveled the mess MS Support did by remote-ing into both my computers. To me it's not Hoodoo, but Voodoo. I'm just glad they're practitioners of OneDrive art.
