I'm having a maddening problem since yesterday: without anything having changed in my system, my workflow or my files, all of a sudden there's this one file that refuses to sync. When I open the Dropbox app, it starts syncing and says something like "10 seconds left", then the time starts increasing: "50 seconds left", "5 minutes left", all the way up to "100+ days left", until Dropbox finally gives up and, without any error messages, simply displays a red "X" next to my file. All my other files are being synced correctly.
I have tried restarting my computer, restarting Dropbox, disabling MS antivirus and firewall, deleting the file from both my hard drive and the Dropbox website and copying it back agan, literally everything. Also, the file is not being used at the time I'm trying to sync it, there are no strange characters in the file name, and the file permissions on my local machine are the same as the other files that are being synced properly.
Funnily enough, I CAN upload the file manually through the Dropbox website, but it will still refuse to sync even when the exact same file is both on the website and my local Dropbox folder.
I am going insane here. I have no idea why this specific file is an issue all of a sudden. I haven't found any case even remotely similar to mine in the forums. Has anybody bumped into this issue before?
