How to remove 6741afb79c635b436c393169e8c1a754 folder from my Ext HDD !

[hulkbuster]

Hello folks , two days back i installed dotnetframework on my friends PC, and after the installation this folder by the name of 6741afb79c635b436c393169e8c1a754 which had amd64 and i386 were created on my External HDD ( i had copied the dotnetframework from my Ext HDD to his D:\ , on checking the attributes it was read only, i changed and unchecked the read only from the Properties and tried to delete it ,still no good.
 I tried it from DOS to remove it too, i dont know what to make of it and how to remove it completly, the Properties doesn't show any file size 0 bytes.
I insatlled Unlocker with the same results,,,,, its really bugging me,,,,

   These files/folder were created after installing Dotnetframwork 3.5 (232 MB), which was needed for the last Giveaway , if u remember, SimplyGoodPictures



What do i do
Any assistance is greatly and warmly welcomed.....

The new MS installers pick the drive with the most free space for their temp stuff extraction, and it was your external drive that won the match
You may need to return to that friend and use the same account on his PC to be able to remove the directory, if you can't after taking ownership of that directory. (That's hiding behind one of several Advanced buttons in that Properties screen) Also be sure not to access the directory with Explorer before your try to remove it, it might get locked by Explorer scanning it's content and also the AV scanning it again.

Open an elevated cmd.exe prompt (THIS HAS NOTHING TO DO WITH DOS!), then run cacls "with the correct arguments" to take ownership of the folder.

...And for those with the Home version of the OS, that aren't entirely comfortable at the command line. You can access the NTFS permissions GUI/Tab in safe mode.
