I'm in the process of switching from Dropbox to Google Drive (for storage purposes) and I had to move roughly 50 - 75 GB of files. Roughly 15% in, the app was slowing down to a crawl so I restarted it. But it didn't continue with the upload. It started to delete files and put them in the trash. I've stopped the process altogether. What should I do so this doesn't continue to happen?
