I am uploading files to Google Drive. One PDF and one MS Word document won't load correctly. I have tried multiple times (both drag and drop and right click to upload), and they show up in my Google Drive folder as files with 0 bytes. The files on my hard drive look fine if I open them on my computer, and the other PDFs and Word docs in the folder (some uploaded today) look fine.
OK, I'm also working on Windows 8. And after many attempts with some troublesome PDF files, I solved in a cumbersome way. First, I sent the files to myself via mail using the web application. Once I got my own message I selected the attached files and click the option that says, send to google drive. Voila!. Not the best solution, but at least a solution that doesn't involve changing machines.
