Agreed. While a few artist keep a few _01 _02 files around, mostly as backup/undo files, my last few years in the industry, they all used some kind of version control (maybe not git, but perforce and svn with their visual tools)
- Really good binary performance(light years ahead of git).
- Proper locking for files that can't be merged(basically everything in the art dir).
- Proxy support for co-located teams.
Also it's very slow for small files, and the filtering is according to file extension.
So e.g. if I have some massive mp3s for (sometimes many minutes of) music but also many (100s-1000s) small ones for sound effects downloading 1000 small mp3s take a couple seconds per file even if each is only ~40kb big (normally download rate is a couple MB/sec).
