Addons: Left over files in Default User Profile


Recommended Posts

I mainly use addons in my RIS installations and have been finding that there have been loads of folders with addon installations files left over in the "Default User" profile that is causing delayed logon times when users log on after a PC has been rebuilt.

On investigating, I find that the folders left over all start 7z with a random 4 character string after it and ends in .tmp















Is there anyway I can delete these files before logon? I tried a script, but the 4 character string after 7z changes all the time.

For that, i'm using a custom cmd file to remove leftover files that i don't want.

Try using the code below. When i tried, it worked.

Save it as Cleanup.cmd and add it to your RunOnceEx.cmd file.


cmdow @ /HID
@echo off
DEL /F /Q "%systemdrive%\Documents and Settings\Default User\7z*.tmp"

Also, i was using this for folder deletions.

del "%systemdrive%\Documents and Settings\Default User\OpenOffice.org 2.4 (tr) Installation Files" /Q /S /F

Well, this way you can delete folders. But this is as much i could do it. This script below deletes files any folders starting with "7z" from within your default users directory.

BUT, if there are any files in that directories, you may need to run the script twice. It first deletes the inner contents of directories. Second run deletes the folders themselves. (Sometimes... 3-4 runs needed.)

I don't know if you can run this at installation stage. But if you can, you can do it by the code below.

wscript DeleteFolders.vbs

Name this as DeleteFolders.vbs and try.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFolders = objWMIService.ExecQuery _
("Select * from Win32_Directory where Name Like '%C:\\Documents and Settings\\Default User\\7z%'")
Set colFiles = objWMIService.ExecQuery _
("Select * from Win32_Directory where Name Like '%C:\\Documents and Settings\\Default User\\7z%\\'")

For Each objFolder in colFolders
errResults = objFolder.Delete

Well, give it a try. Hope it might help you.

I sure learnt something while searching for this. (:

You may improve it yourself.

I dont think that the star a.k.a. asterisk (*) flag will work with RD but with DIR /B it will make a detailed list of all the 7z*.tmp and it will delete them one by one

FOR /F %%I IN ('DIR /B "%SYSTEMDRIVE%\Documents and Settings\Default User\7z*.tmp"') DO RD /S /Q "%SYSTEMDRIVE%\Documents and Settings\Default User\%%I"
