These files are part of Tableau Server's caching functions. The files are created automatically as a sort of paging or swap file, and should not be manually removed, as the process that utilizes them would probably not like that.
Hope this helps!
Thanks. After posting, I found that the cache server and backgrounder were down. After running a cleanup, zip logs, and restart, 110gb was freed up and I no longer have a disk space issue.
thanks again -
