I have just found a folder on the C: drive of my SBS 2011 server that includes "spinstall.exe" along with another random hex num folder that includes many dll files for the install I'm assuming. This folder has a capacity of 4.5GB.

Can this folder be deleted?  I have searched and there is the same spinstall.exe file in the windows/system folder.  I believe this service pack update was for exchange but I guess it could also be for SBS2011 though it still shows SP1.  Exchange is now as SP3.

Please let me know if this is a folder that can be deleted.  I know after many other different installs, folders will be left behind on the C:\ directory were the files were extracted to and installed from.

Thank you in advance for your

Hi,

These file arent be related to Exchange service pack, the file size of Exchange 2010 service pack 1 is 522.2 MB.

These are files extracted from the self-extracting archive of the service pack installer. They indeed should have been deleted upon installation completion. For one reason or the other, this has not been the case.
Please pay attention to CBS log to get more details about Windows Update, log file location: %windir%\Logs\CBS\cbs.logs.
Besides, I find an article about Recovering Disk Space on the C: Drive in Small Business Server 2008, for your reference:

That's Windows file, that can't be Exchange related files.
Run the Disk CleanUp and Include System Files too, that's the correct way to get rid of those unwanted files.

Thank you for your reply.  Just to verify, I am running SBS 2011 and not SBS 2008.  I am not sure if this makes a difference but I just wanted to clarify.

Also, these links look to be desperate measures to save disk space.  I am not in the position of running critically low on disk space.  I don't want to remove or delete files that can potentially corrupt the system.

I just want to confirm that if I delete this folder on C: that it will not effect the system.  I know that after installing applications or updates, the required files are usually stored in system folders such as "ProgramData" or "AppData" (which are not visible by default).

Does the system ever rely on files stored directly on C: (not including users setting install locations manually)?

Just to clarify, I am running SBS 2011 which does not have the Disk Cleanup utility.  I don't know there is any disk cleanup for server operating systems unless they are built into an application such as WSUS, Exchange, SharePoint, etc.

If there is a disk cleanup utility for SBS 2011, please let me know how to access it.

Thank you.

Do you see these files and location on the server?

Okay, I have ran Disk Cleanup but it did not remove the folder on the C drive.

PLEASE ADVISE:  The "spinstall.exe" file is 591KB by itself.  There is a folder (random hex number) along with the "spinstall.exe" with a capacity of 4.35GB.  The "spinstall.exe" file and the 4.35GB folder are contained within a folder (another random hex number) located on the C drive.

So the "spinstall.exe" file is actually 591KB but the 4.35GB folder is also included in the same folder on the C drive.

From the sounds of it, it is an Exchange SP from what was being said about the spinstall.exe file being roughly 500K.

When I ran Disk Cleanup, it did remove 6-9GB of Windows SP Backup files but did not remove the folder in question on the C drive.

So my question remains...  is it safe to delete this folder on the C drive?  I don't want to remove it if it is going to cause problems but if it something left over from an update or it's something that isn't needed any more, I would like to remove.

What is the exact location of those files?
Those (random hex number) folders are nothing but the SP update files, removing them shouldn't cause any issue. But you should only do it when you are running out of disk space and there is no other option you have left to free up some space.

Hi,

As above mentioned, its a Windows update legacy file.

We can move this file from C drive to other disk partition for backup, just in case.
Finally, we can remove it if everything works fine.
