Usually i am happy user of dropbox,
I often use public folder to share files with our team, usually i put the file in folder and withing 5-20 secs it's synced(small files)
but sometimes there are cases when it takes hours, cause the file i need to sync ASAP is in the line with our files for syncing which are not so important for me now.
Is there is any way to force sync specific file ASAP?
