If the devs aren't able/willing to fix it (since 2014), best to get rid of it...
my problem is that i have found no easy alternative that reliably preserves the file names, I use Dropbox to sync my World of Warcraft saved files between my desktop and my laptop.
Dropbox preserves file names and in case of a conflict will preserve the file name for the newer file and will rename the OLDER files.
Google Drive (recently renamed as Backup as Sync) does the opposite - it keeps the older file named as-is and will rename the NEWER file - and it tends to detect conflicts if you as much as sneeze at it - it will immediately stop syncing the proper file and will create a renamed file, appending "(1)" or other numbers to the file name.
Google's approach might be OK for documents but is a total train wreck when you consider the case of LUA script programs (such as WoW uses to save data). These scripts MUST have a very precise file name or WoW hits the fan.
When i used Google Drive for syncing WoW saves i was having random weird missing data, old WoW savedata making a comeback or other such things - and in the end i found it was directly caused by the way that Google was creating surprise random additional files instead of preserving the proper file name for LUA scripts.
