When some programs (including Windows programs) installs things, it may create a temporary folder consisting of
20-30 random letters and numbers in the root drive of the volume with the most free space. This explains why
sometimes the folders are on your C drive or on some other drive - which one has the most free space?
For example you may see a folder similar to or called:
There may be other folders and files under that main temporary folder.
These should normally be removed when the installation is complete, but sometimes they are not - especially
if the installation fails. They are harmless but annoying. You may think something is wrong when there is
not or be afraid the files are really needed. To avoid confusion you can delete the temporary folders.
If your installation failed or the installation does not delete the randomly named folder when it completes
running the installation again will make another randomly named folder.
You may be able to identify the installation (for curiosity) by looking at some of the folder contents and decide
if that installation was okay, just delete the files/folders. If the installation did not work properly for some
reason, running the installation again will just create a new randomly named temporary folder so the old temporary
folder is really of no use.
Sometimes the folders are stubborn to delete. Even if you are an Administrator on the system you may get a
"sharing violation", "access denied", "being used" or similar type message when trying to remove the temporary
folders. Installations sometimes use different permissions than a regular user with Administrator group might
There are many methods to try to remove the folders and some involve third party programs to install or changing
certain Windows settings that may compromise your system security if you don't change them back when you are done.
Booting your system in Safe Mode (pressing the F8 key repeatedly right before XP tries to load) is a good method
to try and remove the folders since it doesn't involve making any changes to your system configuration or
downloading any third party programs.
If Safe Mode does not work you can change the security of the folder to give your user Full Control over the folder
by browsing to it in Explorer, click Tools, Folder Options, View and in the Advanced settings window, uncheck (at
the bottom) Use simple file sharing (recommended), and click OK. This turns off the recommended simple file sharing
on your computer so you will want to turn it back on when you are done.
Right click the stubborn folder, Properties and click the now visible Security tab. Select your user name and
check the box to allow Full Control, click OK to apply the changes.
Now try to delete the folder.
It is a good idea to go back into Explorer and turn back on (Enable) Simple file sharing (recommended) when you
