In my installation of SQL Server there are a number of MSSQL.1, MSSQL.2 and so on folders. My question is hopefully quite simple:
Is it safe to delete these folders?
If I am guessing correctly, the .1, .2, .3 extensions signal that they are old files - similar to the way that log files cycle. The greater issue is that there is a log file in one of them (.6) that 13GB in size - and I would like to delete it, but don't want to accidentally cause myself a problem.
Please excuse my inexperience here - if you can explain to me what they are and anything special i need to do while removing them, I would greatly appreciate it.
