  • Did you launch your file explorer as root? – Henry Mar 23 '15 at 20:18
  • I am sorry, I have no idea what you are talking about, I'm new... – Leonardo Mar 23 '15 at 20:18
  • Try going to the terminal at typing in "sudo nautilus", then press enter. Type your password when prompted, this will open the file explorer (nautilus) and give it root permissions – Henry Mar 23 '15 at 20:20
  • Sorry, but if you're new, then are you sure you really need to delete these? – user300458 Mar 23 '15 at 20:24
  • @ user300458 - yes, I am sure. @ Henry - I will try thanks – Leonardo Mar 23 '15 at 20:25

Launch your file explorer as root using:

gksudo nautilus

This will open your file explorer, and grant it root, so it should be able to view/delete the directory/file.

If you are like me, and don't care about the warnings in this question you can use this instead:

sudo nautilus
  • gksudo nautilus (not sudo) – user300458 Mar 23 '15 at 20:22
  • sudo works as well, I never understood why people used gksudo, it always caused my more trouble because I needed to install it, as it was not included with my system. And I find it more annoying to have to wait for the window to open, then type in my password, possibly blocking other open windows. I prefer if it just asked for my password in the terminal, it's quicker and less obstructive. – Henry Mar 23 '15 at 20:23

  • Edited my answered to include both sudo and gksudo – Henry Mar 23 '15 at 20:32
  • IT WORKED ONLY WITH GKSUDO – Leonardo Mar 23 '15 at 20:58

Try the following: launch Terminal and enter

sudo rm -rf '/path/to/locked/folder'

And be VERY careful with the path to folder!

Steps:

  1. Open Terminal.
  2. Run command:

    sudo su
    
  3. Command above would ask for your password.
  4. Once the correct password is given, you would give following command.

    chmod a+rwx folder/file 
    

    and go to home and just delete the folder/file.

  5. Exit for root user type exit.

  • @Zanna: sudo su works on my system and I didn't change the root account or the sudoers configuration in a relevant way. But it's unnecessary because one could just run sudo chmod ... instead. – David Foerster Oct 25 '16 at 10:02
  • @DavidFoerster I thought I had deleted that comment already! but yes indeed it's completely unnecessary – Zanna Oct 25 '16 at 10:03

    This answer is basically the same as kos' but with less detail and worse practices. – David Foerster Oct 25 '16 at 10:04
  • yeah agree with that too – Zanna Oct 25 '16 at 10:04

The lock symbol means your user currently have no write permission on the file/folder. To change this:

  1. Check the current owner/group/permissions status by right clicking the file/folder, clicking Properties and then switching to the Permissions tab.
  2. Open a Terminal by hitting Ctrl+Alt+t.
    • If you are the Owner of the file (i.e. the Owner field shows your username): add write permission to the owner by running this command: chmod u+w <path_to_file_folder>
    • If you are not the Owner of the file, but you are in the Group group (i.e. the Group field shows your username or a name of a group to which you belong, e.g. sudo): add write permission to the group by running this command: sudo chmod g+w <path_to_file_folder>
    • If you are not the Owner of the file and you are not in the Group group: add write permission to the others by running this command: sudo chmod o+w <path_to_file_folder>
  3. Run exit

And then just delete the file/folder from Nautilus.

Alternatively:

  1. Open a Terminal by hitting Ctrl+Alt+t.
    • Remove the file/folder as root by running this command: sudo rm -rf <path_to_file_folder>

Here is something , that I found was easier to do instead of opening terminal. Right-Click the file and open properties. Then switch to the permissions tab. Then wherever it says Access: change it from whatever it is to Create And Delete Files. This should remove the lock and then you can delete the file normally.
