Is it "safe" to delete any of the subfolders in C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\ from my drive to free up space?

Or is it needed for upgrade/uninstall and other patches? Right now the Update Cache folder contains KB968369 (sp1) which takes up 416mb, which seems like a candidate for freeing up space.

It's 1.3 GB for Server 2012... – romkyns Nov 28 '14 at 0:26
2.5 GB here. It's annoying how inefficient Windows Installer is. It leaves every single update setup package in full somewhere, also in C:\Windows\Installer. No non-MS technology does such stupid things. Need a bigger disk now. :-( – ygoe Dec 18 '14 at 8:09

According to this site, you shouldn't. You can compress it and remove log files, but you shouldn't delete it.

If I hadn't googled for it I would probably have tried searching to see if any of the files were open, and if not, then copied them to a new location for storage until I was certain the server worked well without it, and if there was an issue recopy them over.

Then again I also have been known to delete the hidden/compressed update files in the Windows directory which is also considered bad practice from what some have said and have had no horrible side effects while freeing up hundreds of meg in space.

An alternative would be to look into installing larger drives and expanding your disk partitions. Depending on the role of the server this could be a major project, though, but in the end if you're in need of freeing space on a database server it's probably time to look at upgrading that subsystem, at least.

In this case it's unlikely MS will put out a SP2 for 2008 (as 2008 R2 has been released); but those files would be necessary if a SP2 comes out and he wanted to upgrade. They're also necessary if he ever wants to uninstall. I'd be more worried that he's grabbing at straws like 400mb. – Chris S Jun 23 '10 at 12:44
Actually it's on my dev laptop with an SSD disk, so hard to get more space in there. I tried googling a bit myself but couldn't find a definitive answer. I'll most likely copy them off to backup drive, and if I ever get a weird error when doing installl/upgrade on the SQL server I'll try and remember why :) – Mikael Svenson Jun 23 '10 at 19:45
So have you ever needed those files? It's 1GB in my case and as in your case I'm on small SSD. – Nux Oct 4 '12 at 8:59
