Files safe to delete/move/remove?
 

I am tryin gto free up space on some old servers, and want to delete some
files, can anyone tell me if these are safe to delete/move/remove;

C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix
(other SQL files that I might be able to move?)
C:\Windows\installer\$PatchCache$\
C:\WINDOWS\SoftwareDistribution\Download\
C:\Windows\ie7updates\

(((((((((()))))))))))))
For others who stumble across this forum, here is what I have found so far;

******
These are NOT save to delete, leave these files alone
******

X C:\windows\installer can NOT be removed, although duplicate files ca be
removed. this is used for uninstalls and installs of new apps
X C:\windows\assembly can NOT be removed, this is a .NET folder, do not
play with or compress
X $hf_mig$ can NOT be removed, although it can be compressed. this
directory tells future updates what has already been done

*******
These are safe to be moved/deleted/removed
*******

O $Ntxxxxxxx$ files can be removed from the c:\windows directory
O Attempt to move the page file
O Run the disk clean up utility, and compress old files, and empty the
recycle bins
O The temp directories in the user profiles can be cleaned out, also
check the desktops for downloaded apps for their setup file
O C:\WINDOWS\Downloaded Installations\ These should be safe to remove,
but probably a good idea to leave them alone as the updates may need them, be
careful here.
O Ok to delete log files for Symantec
C:\Documents and Settings\All Users\Application Data\Symantec\Symantec
AntiVirus Corporate Edition\7.5\Logs
Configure History in SSC, right click server>all tasks>Antivirus>Configure
history
C:\Program Files\Common Files\Symantec Shared\Reporting
Agents\Win32\ReporterSvc.log
O Quarantine files can be removed from Symantec, usually here;
C:\Documents and Settings\All Users\Application Data\Symantec\Symantec
AntiVirus Corporate Edition\7.5\Quarantine
O Ok to delete zip files from Symantec, and actually all files in here
C:\Documents and Settings\All Users\Application
Data\Symantec\LiveUpdate\Downloads
O IIS web logs ok to remove C:\WINDOWS\system32\LogFiles\W3SVC1
There is no option to do this automatically, this must be scripted
O Log ok to remove C:\WINDOWS\system32\wbem\Logs\FrameWork.log
There is no option to do this automatically, this must be scripted
