Unknown folders on external drive?
 
Recently, in one of my external hard drives, the following folders have appeared in the drive root:
 
7fb7dac2bb16c4aa9c7238e97b5bcc7c    empty
 
65c8d890d8d994d8302e43b3f93c    empty
 
531a420f86442b4ff51cdb7b   'Setup.exe' inside
 
629d83dea8849fbf3adb1b  have to open with 'admin', folder 'amd64' inside
 
ab9251f6adfb6282d66a83a8  have to open with 'admin',  folder 'amd64' inside
 
b8854913dead8cf1a6
 
Anyone know how and why they appeared, what they are for, and is it safe to delete them? 
 
Thanks!

I responded to your post on the Computer Hope forum.

When some programs (including Microsoft programs) install things, it may create a temporary folder consisting of 10-30 random letters and numbers or random numbers and letters 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 might be on another drive - which one has the most free space?

For example you may see a folder similar to or called:

D:\9470bb12e8a4f3447657236478e41c5

There may be other folders and files under that main temporary folder such as amd64 and i386.

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 and you run the installation again, the installation again will make another randomly named folder.  Sometimes you will see several folders like this and they can all be deleted.

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 have so you may have trouble deleting the folders.

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 Windows loads is a good first 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 none of the above work, try a popular third party tool called Unlocker.  Unlocker will work for any version of Windows.

Unlocker can be downloaded from here:

http://www.emptyloop.com/unlocker/

You may need to use Internet Explorer to get Unlocker to download properly.

Do not be tempted to download or install any other software that promises some miracle on your system.  Just download the correct Unlocker for your system (either 32 bit or 64 bit).

Pay attention when installing Unlocker since it wants to add a bunch of options, addons, shortcuts, and other extras you don't need so be sure to SKIP and DECLINE any free things, or other checkboxes for example:

UNcheck the box to install the Babylon Toolbar and click Next
UNcheck the box to Check for Unlocker updates
UNcheck the box to install the Unlocker Assistant

DO check the box to install the Explorer Shell extension (you are going to need that)

Click Install, you do not need to reboot.

The reason you need to add the Explorer Shell Extension is so when you right click on the offending folder, you will have an Unlocker option to choose.    Explorer Shell Extensions help make up the right click menu when you look at a file or folder.

Right click one of the offending folders and choose Unlocker, then choose the Action (that would be delete) and click OK and you should see a Success message and the folder should be gone.

I would just install Unlocker long enough to clean up those leftovers and then, I then generally use Add/Remove Programs to uninstall Unlocker and all parts of it.  You can always install it again some other day if you need to.

Unlocker can be uninstalled when you are finished using it.

Reboot when you are finished to be sure the annoying folders are really gone.

Thanks everyone for your fast responses.  Once a month I run CCleaner....the next time I run it, I'll see if those folders are 'cleaned'.

You don't need a third party app - just delete the folders yourself.
