I keep my desktop and laptop synced using Dropbox (with the added benefit of online backups).
A couple of days ago, for no apparent reason, Dropbox on my laptop started re-uploading/downloading a massive amount of files (it's currently stuck at "Uploading 745000 files" and "Downloading 69000 files", without much change for a long time.
1. Any idea what happened?
2. How can I completely restart the sync process, *without* having to re-download everything? I have over 450GB on dropbox, and 99.99% of the files are already in sync between online/my desktop/my laptop. I tried deleting dropbox's cache (~/Dropbox/.dropbox.cache) but it didn't change anything. I'm afraid of deleting ~/.dropbox/* because I don't want to cause mayhem or re-download everything? What should I do?
