This similar idea is marked as "Accepted", though I don't know exactly what feature it's referring to... maybe upvote that one as well?

It looks like google drive has file extensions selective sync see:

Dropbox should follow suit asap

edbreen: i wouldn't count on seeing it anytime soon.  That article is dated almost four years ago

Some of the Dropbox competitors have a feature where account admins can choose a list of file types not to sync to dropbox such as .tmp .dat etc. This would be a great feature.  Our company uses software that creates issues with certain file types syncing. 

this is a big deal for a gis user.  i have .lock files that won't sync... and while arcgis is open it's always a red flag.  so annoying dropbox. can you give us an update?
